Top-Programming-Languages-to-Learn-in-2020, Best-Programming-Languages-to-Learn-in-2020

INTRODUCTION

Programming is important for speeding up the input and output processes in a machine. Programming is important to automate, collect, manage, calculate, analyze the processing of data and information accurately.

Programming is important to create software and applications that help computer and mobile users in daily life. Due to all these reasons, it’s really important to learn how to use programming languages in our daily life.

Java, javascript, C#, C++, PHP, Python, Swift, SQL, Ruby, etc. programming languages are the reasons behind the innovations in information technologies. If today we are seeing robots, artificial intelligence, machine learning, bitcoins, blockchain, IoT (Internet of Things), Cloud Computing, etc. new technology and products in the IT industry, then it’s because of programming languages.

So, I'll use bottom down approach to describe you the top 5 programing languages to learn in 2020.

5. SWIFT                                                               

Swift has replaced the Objective-C as the main language for Apple-related software and application. Since it is supported and promoted by Apple so there is an increase in popularity since its inception and as Apple is going to continue with it so if someone is looking for Apple-specific development platform then Swift is going to be a must-know programming language. This is mostly vendor and product-specific language with very less usage outside Apple’s eco-system.

Key Features

• Module stability defines a new text-based module interface file that describes the API of a binary framework.
• Property wrappers introduce a general purpose syntax for defining custom access patterns for property values.
• Opaque result types help hide implementation details in APIs.
• 'Self' can now be used for classes and value types.
• Support for handling and updating diffs on collections of appropriate types.
• Improvements to SIMD and String types.

Open Source

Swift is developed in the open at Swift.org, with source code, a bug tracker, forums, and regular development builds available for everyone. This broad community of developers, both inside Apple as well as hundreds of outside contributors, work together to make Swift even more amazing. There is an even broader range of blogs, podcasts, conferences and meetups where developers in the community share their experiences of how to realize Swift’s great potential.

Cross Platform

Swift already supports all Apple platforms and Linux, with community members actively working to port to even more platforms. With SourceKit-LSP, the community is also working to integrate Swift support into a wide-variety of developer tools. We’re excited to see more ways in which Swift makes software safer and faster, while also making programming more fun.

Swift for Server

While Swift powers many new apps on Apple platforms, it’s also being used for a new class of modern server applications. Swift is perfect for use in server apps that need runtime safety, compiled performance and a small memory footprint. To steer the direction of Swift for developing and deploying server applications, the community formed the Swift Server work group. The first product of this effort was SwiftNIO, a cross-platform asynchronous event-driven network application framework for high performance protocol servers and clients. It serves as the foundation for building additional server-oriented tools and technologies, including logging, metrics and database drivers which are all in active development.

4. GO                                                                           

Go (Golang) is getting popularity as maintain, use and promoted by Google. The motivation of Go development was to address criticism of some of the popular languages and keeping the best of them in one place. Since 2017, Go is moving upward in popularity and with Google support, it is going to enjoy this in coming years. Google is also making Go as a primary language for new projects and replacing other languages with Go, this trend going to make useful and important to learn in coming years so one can pick Go as a new programming language.

Key Features

Binaries:

Go generates binaries for your applications with all the dependencies built-in. This removes the need for you to install runtimes that are necessary for running your application. This eases the task of deploying applications and providing necessary updates across thousands of installations. With its support for multiple OS and processor architectures, this is a big win for the language.

Language Design:

The designers of the language made a conscious decision to keep the language simple and easy to understand. The entire specification is in a small number of pages and some interesting design decisions were made vis-à-vis Object-Oriented support in the language, that keeps the features limited. Towards this, the language is opinionated and recommends an idiomatic way of achieving things. It prefers Composition over Inheritance and its Type System is elegant and allows for behavior to be added without tight coupling the components too much. In Go Language, “Do More with Less” is the mantra.

Powerful standard library:

Go comes with a powerful standard library, distributed as packages. This library caters to most components, libraries that developers have come to expect from 3rd party packages when it comes to other languages. A look at the Packages available in the standard library is good enough indication of the power available in them.

Package Management:

Go combines modern day developer workflow of working with Open Source projects and includes that in the way it manages external packages. Support is provided directly in the tooling to get external packages and publish your own packages in a set of easy commands.

Static Typing:

Go is a statically typed language and the compiler works hard to ensure that the code is not just able to compile correctly but other type conversions and compatibility are taken care of. This can avoid the problems that one faces in dynamically typed languages, where you discover the issues only when the code is executed.

Concurrency Support:

One area where the language shines is its first-class support for Concurrency in the language itself. If you have programming concurrency in other languages, you understand that it is quite complex to do so. Go Concurrency primitives via go routines and channels makes concurrent programming easy. Its ability to take advantage of multi-core processor architectures and efficient memory is one of the reasons while Go code is today running some of the most heavily used applications that are able to scale.

Testing Support:

Go Language brings Unit Testing right into the language itself. It provides a simple mechanism to write your unit tests in parallel with your code. The tooling also provides support to understand code coverage by your tests, benchmarking tests and writing example code that is used in generating your code documentation.

3. Java                                                                     

Java was on rising but fall in 2019, the reason could Kotlin gaining popularity on the Android platform. Java is a good choice for a programming language but now it is under Oracle and Google is promoting Kotlin so it is in the conflicted zone. As a matter of fact still, the large number of the company is using Java and going to continue with Java due to its developers base, framework, and legacy application.

A lot of sites today do not function without Java. It is noteworthy that every year there are more such services. Because of the demand for professionals who are well versed in this programming language, more and more.

Java Benefits in 2020 are:

• object-oriented programming;
• readable and easily manageable language;
• does not require a specific hardware infrastructure;
• good level of security;
• stability;
• automatic memory management. 

Java Disadvantages in 2020 are:

• non-standard interface, which you need to get used to for a long time;
• consumes a lot of memory and reduces hardware performance;
• difficult to learn;
• limited critical delay setting;
• does not support general programming, which increases the amount of work when writing code;
• no possibility to make backup;
• slow. 

What can I say about Java? Strong old fellow, to whom no one has found a replacement. It is a little behind the current pace of technology development. But thanks to the high-quality code compilation and high stability, it still occupies high positions. Recently, there has been a decline in interest in Java, but it is still one of the most desirable languages among programmers.

2. JavaScript                                                           

Javascript is the front-end programming language most widely used in the world for developing web applications like SPA or MPA. It allows you to create all the animations, set up a lot of buttons, manage multimedia and much more. In other words, Javascript is the unconditional basis for front-end development and its frameworks Angular, React and Vuew.

Javascript benefits in 2020 are:

• high speed due to the ability to run through the browser on the client side;
• easy to learn;
• it is perfectly combined with other languages;
• the ability to create a crowded interface;
• annual updates.

Javascript Disadvantages in 2020 are:

• since the code is executed on the client side, this somewhat reduces the security of the user's computer;
• scripts can be executed differently depending on the browser.
• A unique feature of Javascript is a set of functional frameworks. So, Node.js with Express.js allows you to use this programming language to run server-side scripts.
• 80% of companies require candidates for work knowledge of Javascript and the presence of experience in its environment. That’s why this language is a constant trend for several years.

1. Python                                                                 

   One of the most popular server-side programming languages. According to the latest PYPL statistics, users most often seek training and assistance in working with Python. As a rule, it is used to write scripts and plug-ins. For example, through Python are recorded episodes and actions of characters in games.

It is a universal language with easy to read code. Due to the features of the syntax, programmers need to perform fewer actions to create a plugin than in Java or C ++. Brands like Instagram and Surveymonkey use it. Google, Netflix and Quora cannot do without Python.

Python Benefits in 2020 are:

• very simple code;
• the possibility of asynchronous coding (alternating the execution of processing cycles);
• supports most libraries;
• free;
• open source;
• object oriented.

Python Disadvantages in 2020 are:

• despite the simplified way of writing code, many processes run long enough;
• weak for mobile application programming;
• requires many tests to completely eliminate errors. 
• Many advice Python to absolute programming weasels for initial learning. Ideally, after 2-3 lessons, you can write a simple code.

Python ratings are growing noticeably. In the past, statistics put it in 4-5 places, but in February 2019 it was already in the first place in the number of search queries. More detailed statistics will be only at the end of the year. But now we can confidently say that this is the main trend among programming languages.

Apart from these Top 5 Programming Languages, there are 2 more we are including as bonus for learning and getting good job in 2020.

1. C#                                                                        

It is an amazing programming language that can teach you a lot about both OOP and Functional Programming.

There is an amazing piece of advice for conferences and books, but it applies to programming languages too:

“Consume anything by a relevant author”

In this case, that author is the genius creator of C# Anders Hejlsberg:

He also created TypeScript. You should learn that too ;)

C# has a great community, and it has grown into the open-source with .NET Core.

Not even mentioning the language longevity is supported by the strongest corporation in the world = Microsoft, currently valued at ~1 trillion $.

2. PHP                                                                     

PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

Instead of lots of commands to output HTML (as seen in C or Perl), PHP pages contain HTML with embedded code that does "something" (in this case, output "Hi, I'm a PHP script!"). The PHP code is enclosed in special start and end processing instructions <?php and ?> that allow you to jump into and out of "PHP mode."

What distinguishes PHP from something like client-side JavaScript is that the code is executed on the server, generating HTML which is then sent to the client. The client would receive the results of running that script, but would not know what the underlying code was. You can even configure your web server to process all your HTML files with PHP, and then there's really no way that users can tell what you have up your sleeve.

The best things in using PHP are that it is extremely simple for a newcomer, but offers many advanced features for a professional programmer. Don't be afraid reading the long list of PHP's features. You can jump in, in a short time, and start writing simple scripts in a few hours.

Although PHP's development is focused on server-side scripting, you can do much more with it. Read on, and see more in the What can PHP do? section, or go right to the introductory tutorial if you are only interested in web programming.
