Programming languages in great demand in 2020

The programming language is a way to communicate with electronic devices in digital format. They enable us to develop online solutions such as- mobile applications, web applications, and games which people use in their daily life. Computer programming will remain in existence forever as it is one of the strongest tools for problem-solving and helping people get what they want.
Computer Programming …?
Computer Programming is the process of designing, writing, testing, debugging, and maintaining the source code or computer programs. It is written in any of the programming languages (such as C++, C#, etc.). Its purpose is to create a set of instructions that computers use to perform specific operations. The process of writing source code often requires expertise in many different subjects – knowledge of the application domain, specialized algorithms ( data structures), system software, and logical reasoning skills.
We are living in the digital era where the new advancements in technology are blooming non-stop and the use of electronic devices is growing exponentially worldwide. Hence, it is almost guaranteed that there are going to be endless lucrative jobs in the computer programming industry.
Here are a few programming languages recommended for coders who want to achieve bigger in 2020.

  1. Python – the most versatile programming language
    Python is an easy-to-learn and uses a programming language that offers simple and interactive coding, making it powerful enough to build versatile applications. It has a large developer community that makes application development easy even for a novice user. It is very productive. YouTube, Instagram, Pinterest are all built-in Python.
    For instance, Python gives powerful toolset for Statistics, and Computational Science with various open-source libraries like NumPy, Pandas, SciPy, Scikit-Learn. For back-end web development, the Django framework is used which is feature-rich. Other Python libraries such as TensorFlow, Keras, PyTorch, and OpenCV are used in data science, machine learning, etc. It’s also used to create neural networks for artificial intelligence.
    Drawbacks :
    It is not ideal for mobile app and game development due to the consumption of more memory and its slow processing speed.
    Python’s database access layer is primitive and underdeveloped in comparison to JDBC and ODBC technologies.
  2. Kotlin – The JAVA alternative
    Kotlin is an easy-to-learn and open-source language for Android app development, web development, and server-side development. It runs on JVM (Java virtual machine) and offers the developer productivity close to Python’s. Due to this, it is now the main language for android app development.

It effortlessly combines object-oriented and functional programming features within it and completely interoperable with Java. For instance, brands like Coursera and Pinterest have already moved to Kotlin.
Some Java issues addressed in Kotlin
Null Safety – Kotlin through the type system eliminates NullPointerException and helps in boosting data consistency.
Data classes – App developers now can add data in front of the class, which will work as the model class. This model class without any getters and setters will be able to reach out to the members on its own.
Clean and compact syntax – To be more precise, Kotlin can get things done with fewer lines of code that make it more reliable with fewer errors, than Java.
It supports functions that can be extended and operator overloading too.
It offers Type inference for variable and property types and Declaration-site variance & Type projections.
Kotlin does not have checked exceptions, static members,non-private fields. Also, it provides no support to wildcard-types and Ternary operator ( a ? b: c).undefined

3.Java – “Write Once, Run anywhere”
Java is one of the most popular programming languages used for developing server-side applications. It is a practical choice for developing Android and iOS apps, web applications, etc.
This object-oriented programming language does not require a specific hardware infrastructure, is easily manageable, and has a good level of security. No wonder, most of the companies rely on Java for their desktop applications and backend development projects.
Drawbacks :
Java does not have Extension functions, Null-safety, and Data classes.
It does not offer Separate interfaces for read-only and mutable collections and Operator overloading support.

4.JavaScript/ NodeJS – Making websites interactive
JavaScript (also known as NodeJS) is a popular language for server-side and client-side programming (interactive front end apps – browser side). It is compatible with several other programming languages and is extremely versatile, allowing you to create feature-rich applications, etc.
Owing to its high speed, Netflix, Uber, etc use JavaScript to create dynamic web pages that are secure and fast.
JavaScript is omnipresent in today’s digital environment. Hence, learning this language makes complete sense.
The copy or equivalent method is absent. It allows only single inheritance.
Might be interpreted differently by different browsers.

5.TypeScript – ‘ Javascript that scales’
TypeScript, a superset of JavaScript is an object-oriented language. Further, it is well-structured and easy to learn. Its extended toolbox makes application development quick and is used for developing large applications with a strict syntax.
It is essentially JavaScript, but less complex. Also, it allows static types (for easier error identification) and provides improved functionality without reducing its effectiveness, making it a great choice for new programmers.

Go is fairly a new system-level programming language that has a focused vocabulary and simple scoping rules. It blends the best aspects of functional programming and object-oriented styles. Go is the fastest-growing language on Github, meant to replace languages like Java and C++.
This speed advantage has made Go a critical component of cloud infrastructure.

Swift is a general-purpose compiled programming language developed by Apple that offers a simple syntax and is fast, secure, and easy-to-learn. Owing to its versatility, it replaces Objective-C the main language for Apple-related applications.
Swift is the premiere coding language that helps developers create iOS apps within a short time.
Summing Up
Knowing which languages are gaining popularity can ensure better career growth and help job seekers prioritize learning them first.
Now if a school, and college students learn to code as early as possible, it will greatly help them to create next big things like WhatsApp, Google, etc that can create greater impact and change the world.
