The best back-end web development languages include the following:
Java: Used for projects that involve a lot of data, Java is a programming language created and released by Sun Microsystems in 1995. Known as a fast, secure, and reliable language, Java is used for mobile computing, games, and desktop computing.
PHP: A widely-used open-source scripting language, Hypertext Preprocessor, or PHP, is a popular web development language that can be inserted into HTML. PHP manages dynamic content, session tracking, databases, and e-commerce websites.
Python: Known as a general-purpose, high-level programming language, Python is ideal for back-end development, data science, and writing system scripts.
Ruby on Rails: Written in Ruby, Ruby on Rails is a server-side tool that gives web developers a framework that delivers default structures for a database, web services, or web pages.
.NET: An open-source developer platform, .NET was developed by Microsoft and runs mostly on Microsoft Windows. .NET features an extensive class library and works in conjunction with several other programming languages.
While there isn’t one language that is the best for back-end web development, partly because multiple languages are used on a single website, the above languages are the most popular and commonly used by developers.
