Programming language in computer programming is needed for the same reason you need a natural language in your everyday life to communicate and simplify things.
Programming languages are an interface between humans and computer, they allow us to communicate with computers to do awesome things.
This article guides you to build C, C++, Java, Node.js and Do applications for eSOMiMX6 device(s).
C is a programming language initially developed by Dennis Ritcher between 1969 and 1973 at Bell Labs, and used to re-implement the Unix operating system.
C is a structured programming language. The language was designed to support cross-platform programming. Compilers, libraries and interpreters of other languages are often implemented in C.

In 1979, Bjarne Stroustrup, a Danish computer scientist, began work on “C with Classes”, the predecessor to C++. In 1983, “C with Classes” was renamed to “C++”, adding new features that included virtual functions, function name and operator overloading, references, constants, type-safe free-store memory allocation (new/delete), improved type checking, and BCPL style single-line comments with two forward slashes (//).
Furthermore, it included the development of a standalone compiler for C++, Cfront. In 1985, the first edition of The C++ Programming Language was released, which became the definitive reference for the language, as there was not yet an official standard. The first commercial implementation of C++ was released in October of the same year.
C++ is an object-oriented programming language. It was designed with a bias toward system programming and embedded, resource-constrained and large systems, with performance, efficiency and flexibility of use as its design highlights.

James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time. The language was initially called Oak after an oak tree that stood outside Gosling’s office. Later the project went by the name Green and was finally renamed Java. Gosling designed Java with a C/C++-style syntax that system and application programmers would find familiar.
Java is a general-purpose computer programming language that is class-based. It is both compiled and interpreted. It is intended to let application developers “write once, run anywhere” (WORA). The compiled Java code can be run on any platform.

Python was conceived in the late 1980s, and its implementation began in December 1989 by Guido van Rossum at Centrum Wiskunde & Informatica in the Netherlands as a successor to the ABC language capable of exception handling and interfacing with the Amoeba operating system.
Python is a widely used high-level programming language for general-purpose programming. It is an interpreted language.

Golang is a programming language initially developed at Google in year 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. Go programming language is a statically-typed language with syntax like that of C. It provides garbage collection, type safety, dynamic-typing capability, many advanced built-in types such as variable length arrays and key-value maps. It also provides a rich standard library.
Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multi core and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It’s a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
