JavaScript
JavaScriptis a multi-paradigm, dynamic language with types and operators, standard built-in objects, and methods. Its syntax is based on the Java and C languages — many structures from those languages apply to JavaScript as well. JavaScript supports object-oriented programming with object prototypes and classes. It also supports functional programming since functions are first-class objects that can be easily created via expressions and passed around like any other object.
This page serves as a quick overview of various JavaScript language features, written for readers with background in other languages, such as C or Java.
Python
What type of language is Python? Python is an interpreted, object-oriented, high-level programming language with dynamic semantics developed by Guido van Rossum. It was originally released in 1991. Designed to be easy as well as fun, the name “Python” is a nod to the British comedy group Monty Python. Python has a reputation as a beginner-friendly language, replacing Java as the most widely used introductory language because it handles much of the complexity for the user, allowing beginners to focus on fully grasping programming concepts rather than minute details.
Python is used for server-side web development, software development, mathematics, and system scripting, and is popular for Rapid Application Development and as a scripting or glue language to tie existing components because of its high-level, built-in data structures, dynamic typing, and dynamic binding. Program maintenance costs are reduced with Python due to the easily learned syntax and emphasis on readability. Additionally, Python’s support of modules and packages facilitates modular programs and reuse of code. Python is an open source community language, so numerous independent programmers are continually building libraries and functionality for it.
Python Use Cases
- Creating web applications on a server
- Building workflows that can be used in conjunction with software
- Connecting to database systems
- Reading and modifying files
- Performing complex mathematics
- Processing big data
- Fast prototyping
- Developing production-ready software
Go (or GoLang)
Go (or GoLang) is a procedural programming language. It was developed in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson at Google but launched in 2009 as an open-source programming language. Programs are assembled by using packages, for efficient management of dependencies. This language also supports environment adopting patterns alike to dynamic languages. For eg., type inference (y := 0 is a valid declaration of a variable y of type float).
Go is a statically typed, concurrent, and garbage-collected programming language created at Google in 2009. It is designed to be simple, efficient, and easy to learn, making it a popular choice for building scalable network services, web applications, and command-line tools.
Go is known for its support for concurrency, which is the ability to run multiple tasks simultaneously. Concurrency is achieved in Go through the use of Goroutines and Channels, which allow you to write code that can run multiple operations at the same time. This makes Go an ideal choice for building high-performance and scalable network services, as well as for solving complex computational problems.
Another important feature of Go is its garbage collection, which automatically manages memory for you. This eliminates the need for manual memory management, reducing the likelihood of memory leaks and other bugs that can arise from manual memory management.
Rust
Rustis a multi-paradigm, general-purpose programming language that emphasizes performance, type safety, and concurrency. It enforces memory safety—meaning that all references point to valid memory—without a garbage collector. To simultaneously enforce memory safety and prevent data races, its “borrow checker” tracks the object lifetime of all references in a program during compilation. Rust was influenced by ideas from functional programming, including immutability, higher-order functions, and algebraic data types. It is popular for systems programming
Software developer Graydon Hoare created Rust as a personal project while working at Mozilla Research in 2006. Mozilla officially sponsored the project in 2009. In the years following the first stable release in May 2015, Rust was adopted by companies including Amazon, Discord, Dropbox, Google (Alphabet), Meta, and Microsoft. In December 2022, it became the first language other than C and assembly to be supported in the development of the Linux kernel.
Rust has been noted for its rapid adoption, and has been studied in programming language theory research.
Mobile development languages (Swift and Kotlin)
For native mobile app development, Swift is essential for iOS/Apple, while Kotlin reigns supreme for Android. These languages are relatively easy to learn and offer robust features for mobile app creation.
It’s important to note that the “best” programming language depends on your specific goals and interests. Consider the type of applications you want to build, your career aspirations, and your learning preferences when choosing a language to learn.
