Java is an object-oriented language created to have as fewer execution dependencies and is designed to let developers write once, run anywhere (WORA), which means that compiled code can work on almost all platforms that support Java. Java applications are compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is alike to C and C++, however, has fewer low-level facilities than either of them. In 2019, Java was one of the most accepted coding languages as per GitHub, especially for client-server network applications, with a recorded 9 million developers.
C is a procedural coding language initially developed by Dennis Ritchie in 1972 to write an operating system. The key features of C language comprise low-level access, simple keywords assemblage, and a clean style that makes C suitable for system programmings like compiler development.
C++ is a cross-platform language used to build high-performance applications and was designed by Bjarne Stroustrup, as an expansion of the C language. C++ gives developers a higher control over system resources and memory. It is one of the worldwide programming languages and can be found in today's operating systems, GUIs, and embedded systems.
Moreover, it is an object-oriented programming language which gives a transparent structure to programs and enables code to be reused, lowering expansion costs and is portable and can be used to improve applications that can be adapted to multiple platforms.
Python is an interpreted, high-level coding language created by Guido van Rossum in 1991, Python's design conception emphasizes code readability with its use of significant whitespace. Moreover, Python uses an object-oriented strategy to help programmers write clear, logical code for small to large-scale projects.
Python is coded dynamically and supports multiple programming paradigms, including procedural and functional programming. It is often expressed as a batteries-included language because of its comprehensive standard library.
Lisp is a second-oldest high-level programming language with fully parenthesized prefix notation developed in 1958. Only Fortran is older, by one year. The commonly used general-purpose Lisp dialects are Clojure, Common, and Scheme.
Lisp was designed as a mathematical notation for machine programs, supported by Alonzo Church's lambda calculus model and quickly became the favored programming language for artificial intelligence (AI) research. Moreover, Lisp pioneered in IT, including tree data arrays, predefined storage management, dynamic coding, higher-order functions, repetitions, self-hosting compiler, and read–eval–print loop.
Ruby is a high-level interpreted coding language designed in the mid-1990s by Yukihiro Matsumoto from Japan. It is a dynamically typed and garbage stored language that supports multiple programming paradigms, including procedural, object-oriented, and functional programming. Ruby was designed as a unification of Perl, Smalltalk, Ada, Eiffel, Basic, and Lisp.
Lua is a high-level, multi-paradigm language designed for embedded use in applications and is cross-platform, since the interpreter of compiled bytecode is written in ANSI C, and Lua has a simple C API.
Lua was built-in 1993 as a language to meet the hike in customization and provided the facilities of procedural languages, but more complicated features were not included, and it included mechanisms for extending the language, permitting programmers to implement such features. Since Lua was intended to be a general extension language, the developers of Lua focused on improving its speed, extensibility, and easiness in development.

Therefore, companies are looking for suitable candidates that will not only fit to work in their corporate sector but also provide them with new-age ideas and solutions for a multitude of problems.
COBOL is the short form for Common Business Oriented Language, which was designed by the US Department of Defense, in a conference, formed CODASYL (Conference on Data Systems Language) to create a language for business data processing needs which is presently known as COBOL.
COBOL is employed for writing application codes and it's not possible to apply it to write system software and applications like those in the defense and insurance domain which demands huge data processing execute extensive use of COBOL.
Clojure is a modern, dynamic, and functional dialect of the Lisp language on the Java platform and treats code as data and has a Lisp macro system. Presently, the development process is community-driven and advocates immutable data structures and encourages designers to be explicit about running identity and its states. Moreover, this focus on coding with immutable values and explicit progression-of-time constructs is meant to facilitate generating extra robust, concurrent, programs that are fast.
Elasticsearch is a shared, open-source search and analytics engine for all sorts of data and is built on Apache Lucene in 2010 by Elasticsearch N.V. Elasticsearch is the main element of the Elastic Stack, an assemblage of open-source tools for data collection, storage, analysis, and visualization. Elastic Stack generally referred to as the ELK Stack, Elastic Stack comprises a collection of lightweight shipping agents known as Beats for transferring data to Elasticsearch.
Erlang accepted interchangeably with Erlang/OTP (Open Telecom Platform) is a general-purpose parallel functional programming language and a garbage-collected runtime system consists of the Erlang runtime system, several ready-to-use components (OTP) designed in Erlang, and an assemblage of design principles for Erlang programs. Such a runtime system is designed for systems with traits such as; distributed, fault-tolerant, soft real-time, highly available and hot-swapping systems.
Go programming also known as Golang is an open-source programming language developed by Google, a statically-typed compiled language supports parallel programming, i.e. it supports running multiple processes simultaneously, which is achieved through channels, goroutines, and so on. Go programming has garbage accumulation which itself does the memory management and provides the deferred execution of functions.
Go also called Golang, a statically compiled and typed coding language developed in Google by Robert Griesemer, Rob Pike, and Thompson is syntactically alike to C, but with memory protection, garbage accumulation, structural typing, and CSP styled concurrency. The two common implementations of Go programming are; Google's self-hosting compiler toolchain and the gccgo, which is a GCC frontend.
Google dart, a client-optimized language for various platforms designed by Google is generally utilized for developing mobile, desktop, server, and network applications. Google's dart is an object-oriented garbage-collected language with C-style syntax and can compile to either native code in addition to supporting interfaces, mixins, abstract classes, reified generics, and type inference.
Haskell is a general-purpose functional programming language with type inference and lazy evaluation developed to be suitable for teaching, research and industrial application, Haskell has pioneered several advanced programming language features. To exemplify, type classes, allow type-safe operator overloading, proposed by Philip and Stephen were first executed in Haskell, and its main implementation is the Glasgow Haskell Compiler and named after logician Haskell Curry.
Pascal is a procedural programming language, by Niklaus Wirth is a language meant to encourage reliable programming practices practicing structured programming and data structuring and is named after a French mathematician and physicist, Blaise Pascal. Pascal was developed on the pattern of ALGOL 60 language and associated in the process of promoting the language as part of the ALGOL X efforts and contributed a version known as ALGOL W, which was not admitted, and the ALGOL X process bogged down and in 1968, Wirth chose to abandon the ALGOL X process and further enhance ALGOL W, delivering this as Pascal in 1970.
Perl is a category of high-level interpreted dynamic coding style, where the term Perl relates to Perl 5 until 2019 and is also connected to its redesigned sister language, Perl 6, before the name was modified to Raku in October 2019. Among various backronyms in practice for Pearl, including Practical Extraction and Reporting Language, it was formerly developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier and since then, it has undergone many changes and revisions. Raku, which originated as a redesign of Perl 5 in 2000, eventually evolved into a distinct language moreover, both languages continue to be developed autonomously by different developers and borrow ideas from one another.
R programming, an open-source software platform for statistical computing and graphics bolstered by R Foundation and is employed among statisticians and data miners for improving statistical software and data analysis. Polls, information mining surveys, and investigations of scholarly literature databases present substantial progress in popularity; by February 2020, R stands 13th in the TIOBE index, which is a measure of the reputation of programming languages.
Rust is a multi-paradigm coding language for safe concurrency is syntactically alike to C++ but is developed to provide better memory safety while maintaining high performance.
