As one of the most popular programming languages on the internet, javascript has many uses. It is a scripting language that can be used to make websites interactive and dynamic. Along with hypertext markup language (HTML) and cascading style sheets (CSS), it forms the foundation of web development. Its unique feature is that it can be executed directly in a user’s browser without the need for downloading an additional program.
The code is written in plain text, which makes it easy for anyone to read and understand. In contrast, other programming languages need to be compiled to be executable. JavaScript is interpreted by a type of program called a parser, and this is provided by most web browsers. As such, it’s very fast to execute and is also more portable than other languages.
Unlike other languages that use a purely procedural approach, javascript is object-oriented. It has a large library of functions that can be used to create complex applications and to perform common tasks. This makes it a very powerful and flexible tool to have in your arsenal as a developer.
