Swift is a powerful is 2.6x faster than Objective-C and 8.4x faster than Python. As a compiled language Swift is as fast as C++. It has automatic Memory Management.  As this is only the programming language used for Apple, it is the most demanding language. Swift is ranked as one of the most popular programming languages. 


 3. Scala: Scala is the short form for Scalable Language. Scala is a High-level language, it is a combination of both Object-oriented Programming and functional programming.

Scala has features of both Oop’s and functional Programming. Scala is a statically typed language that helps to avoid bugs in complex applications.

Scala has easy syntax for user-defined functions and supports higher-order functions. It allows nested functions.

Scala is compiled to Byte-Code and executed by Java Virtual Machine(JVM) Which helps you to build a High-Performance system with Huge Libraries. 

Scala is mostly used in Web Applications and there are some most popular scala web frameworks.

  1. Lift framework.

  2. Play framework.

  3. Bowler framework.

Most developers use “IntelliJ IDEA IDE” for scala because of the great user interface.


Go: Go is an open-source programming language and is available for all operating systems. Is it an open-source programming language that helps to build simple, reliable, and efficient software.

Go was previously built for programs related to networking and infrastructure. Go was designed to replace high-performing server-side languages like java and c++.but today Go is used for applications like cloud and server-side applications, command-line tools, DevOps and more…..

Go Lang has powerful standard libraries and toolsets.

Go is used as a Programming language in Artificial intelligence and data science.

Some uses in robotics and games. 

Go is popular because it is simple, and to build high performing applications.


Python: Python was invented in the year 1991. It is one of the most popular programming languages in today’s world. Python is interpreted, Dynamic type, Object-oriented, scripting language. It is highly productive as compared to other programming languages like C++ and Java.

Python is popular for its simple programming syntax, English-like commands and code reliability. Python is an interpreted language it executes line by line code this makes python an easier and efficient programming language.

Python has different modules based on their use. it is used in artificial intelligence and machine is also used in data science, UI design also used VFX and graphic design.

Python is a simple language to learn without any prior coding experience.

It has a great standard library. You can create a Graphical user interface by using the Python language and it has a huge number of GUI frameworks.


As seen in the above list, which covers only five programming languages out of many. The above listed five languages are based on my preference. There are many other languages to learn based on the requirement. There are many online training platforms to learn these programming languages.
