JavaScript is an object-orientated programming language used to create interactive web pages. It is one of the three core technologies used on the World Wide Web. The other two are HTML and CSS.
Advantages of JavaScript
Simplicity
JavaScript has a simple structure that makes it fairly easy to learn and implement. It runs faster than some other languages and errors are also easier to find and correct.
Speed
JavaScript executes in the web browser without having to connect to a server. Web browsers also allow JavaScript to compile code during program execution.
Compatibility
JavaScript is compatible with other languages like PHP, Perl and Java.
Popularity
There are many resources and forums available to help beginners learn and improve their skills. Visit MDN Web Docs if you want to learn JavaScript or just get more information.
Server Load
Because JavaScript works on the client-side, it reduces the requests sent to the server. Data validation is generally done via the browser and updates only apply to certain web page sections.
Updates
The JavaScript developers and EMCA International work continuously on updates and create new frameworks and libraries. This ensures that JavaScript remains relevant within the industry.
