Some people believe that programming languages will be the future language and everyone must learn them.

As programming languages bring tons of opportunities, the trend for learning them is at peak. And people are shifting from other professions to programming as the payroll is sky-high in this job.

While there may be many languages in the market, there are few languages that are mostly used and desired by the programmers.

But before that, let’s discuss some of the basic things about programming.

What is a programming language?

programming languages

Computing languages are a set of instructions that guides a computing device. It is a type of language which is mostly used in computer programming to apply algorithms.

How much will I earn from programming?

The salary depends upon the kind of qualification you have but the average median salary of programmers in 2019 was recorded to be above $86k annually. Whereas, lowest 10 percent workers were given slightly less than $50k per annum and highest 10 percent programmers were paid just above $140k yearly. Which in comparison with other professions is very high.

So here are some of the best, most demanded and highest paying programming languages in 2021.

Python

Python is a widely used general-purpose high level programming language which is used in website development, data analysis, web applications, deep learning, and GUI applications.

Some of the popular services, like Youtube, Quora, Instagram and Reddit, were created using Python.

The fact that Python uses english keywords in place of punctuation makes it easier for the programmer to write an application without adding further codes.

Python also allows various ways of programming like object oriented and structured programming that makes it easier to create a heavy application. 

In addition, it supports various platforms and a code from one system can be copied to another without editing.

Python has its own framework, libraries and modules that increases developing speed and reduces the cost. The salary of python developers surged by 14% in four years.

On the basis of a survey in 2020, high level python programmers earn as much as $120K per year in the US.

With the beginning salary of $74k which reaches to $100k for mediocres, definitely python is one of the highest paying programming languages.

However, Python cannot be used in mobile computing making it harder for programmers who use only a smartphone to code.

It is also slower than many other programming languages which may not be ideal for impatient people. 

Go

Go or Golang, developed by google in 2007, is one of the fastest growing programming languages with beyond a million users globally.

Developers of Go, Robert Griesemer, Rob Pike, and Ken Thompson, designed this programming language by fitting different valuable features of C++, Python, Javascript and by using a similar type of syntax like C language.

This open source programming language also provides various tools, Gofmt, Gorun, Goget and Godoc, in order to comfort the Go users. Unlike many coding languages out there, the codes and execution in Go is extremely fast which saves a lot of time.

The fact that an interpreter is not needed to change the codes in one’s native machine language benefits by increasing the performance and reducing the cost to make an application. 

The easiness and cost effective nature of Go programming language has made American Express, Salesforce, IBM, Target, Twitch, Netflix, Twitter, Uber, and Dropbox adopt this language for coding. 

Javascript

Javascript is a high level text based programming language that is mostly used to create web browsers, mobile applications and games.

This object-oriented language acts as a bridge in between a user and the web pages by creating communicative elements. 

For instance, Youtube’s search box, the limited offers countdown on Amazon or Facebook logo which when pressed refreshes the newsfeed.

These types of elements are created using Javascript by front end web developers and popular websites like google, youtube, facebook, amazon and wikipedia use it at the front end of their site.

Although, it is also used at the back end with the use of NodeJS. 

World Wide Web was too designed using Javascript, as it’s one of the main programming languages, together with HTML and CSS.

This programming language also comes with a built in interpreter meaning extra codes are not required to get the output.

Faster loading of servers, fewer code lengths,  As per an American website, the highest paid salary for Javascript programmers is just above $117k annually.

 C, C++ & C#

All three of these are widely popular programming languages who are completely different from each other.

 C being one of the oldest low level programming languages as it was first published in 1978.

After which it became the foundation of many languages like C++, C#, Python, Java, JavaScript, Perl, PHP, Verilog, D, Limbo, C shell and Go.

That’s why many programmers will still suggest you learn C, before putting your hands on other programming languages.

It can do many operations and the code doesn’t need to be changed when using it in different machines.

In addition, the structured programming lets easier maintenance and testing.

In contrast, the mistakes can only be detected after writing the whole program making it difficult for the programmer to check the code.

Also, it doesn’t have exception handling which complicates finding the error.

C++ is a standard form of C programming language, and is also known as “C with classes”, having the feature of procedural and object orientation.

It is used to develop games, browsers and operating systems. Many companies, Morgan Stanley, Microsoft, Google, Mozilla, Rockstar Games, MySQL and MongoDB, have been using C++ to develop different applications.

Quite difficult to understand without having a basic idea of C language, the memory needs to be managed manually. 

C#, pronounced as C sharp, is a high-level programming language developed by Microsoft in 2001 that uses .NET framework.

The name C# was taken from a musical note. It can be used to make various services like web applications, online sites, Games, database applications, desktop applications and so on.

Except being easy to learn and operate, It has astonishing features like .NET developer library, imperative, strong typing, declarative, object-oriented and component-oriented programming.

The latest version 9.0 was released on May 20, 2020. 

SWIFT

SWIFT is the latest programming language developed by Apple in 2014 specially for their applications like iOS, macOS, watchOS, tvOS, and Linux.

So, if you’re interested in apple app and software development then SWIFT is a suitable programming language for you.

The most important advantage of using this language is that its  memory is managed automatically and various latest features can be added easily.

SWIFT can be used by anyone as it is an open source programming language that is extremely fast, safe and easy to use. 

Apple claims that SWIFT is 2.6x faster than Objective-C and 8.4x faster than Python 2.7. Various well known apps-Lyft, Khan Academy, Clear, Sky Guide, LinkedIn, Kickstarter, Eventbrite and Hipmunk were created using SWIFT.

Since it’s release, it has undergone many updates and the latest version 5.2.5 was released on August 5, 2020.  

Even though it is the youngest in this list, the wage of Swift programmers is quite high with a median salary of upto $58,000 worldwide and roughly $126,000 in the US.
