Programming languages are systems of notation for writing computer programs. Just as human beings interact with one another in different languages, there are different syntaxes for instructing computers to carry out different operations or functionalities. Every programming language has its own unique notation and syntax for interacting with the computer system.

We established in the introductory week of the Backend Development track in the Learnable '22 internship, that JavaScript is a language that is mostly used for client-side and server-side developments, respectively. However, we will be reviewing the general purposes of other programming, or let me say 'coding languages.'

Python

Python is a high-level language that runs on an interpreter that relays the instructions to the computer in binary (machine language).

The purposes of Python include the following:

• Server side development.

• Machine Learning.

• Data Science.

• Data Visualization.

• Games development, etc.

C Programming

C is a low-level language that is directly executed on a compiler. General purposes of C include:

• Software Development.

• Data Structures & Algorithms.

• Memory management.

• Pseudo coding, etc.

C++

C++ is a language that evolved from C to include new syntax and functions. C++ serves the following functions:

• Development of Operating System Softwares.

• Memory process.

• Unity Games development.

• Object Oriented programming.

Java

With extra emphasis, Java is not to be mixed with JavaScript. It can be likened to saying that Ham is not the same thing as Hampster. Java is a versatile language that can be used for:

• Web Development.

• Games development.

• Android development.

• Object Oriented programming.

R

R is a language with syntax similar to Python but is entirely different. R is generally used for statistics and data analysis.

Other Top Languages

There are many others, such as Kotlin (for Android development) and Dart (for developing cross-platform apps on the Flutter framework).

PHP is another language used for backend development. Swift is used for developing iOS mobile apps.

Other common programming languages include Julia, Scala, Golang, Ruby, and so on. However, the versatility of JavaScript as a programming language can never be overemphasized.
