Javascript, which is commonly abbreviated as JS is a common and primary programming language which is used alongside HTML and CSS as part of a website or web based app.
It is used for the majority of websites on the internet and normally operates as a client-side programme or within the browser as part of the user interface while the user is viewing the HTML document or web page.
Javascript should not be mistaken for another programme called Java which is vastly different in terms of design, even though both languages have some similarities such as the name and the syntax which they use.
Most websites use it as a client-side language for web page behaviors which can include:
- Animations
- Dynamic Search
- Transitions
- Cursor Functions
- Timers
- Zoom and Magnification
Javascript can also be used to build web servers and develop server applications using frameworks built on node.js, which is is Javascript runtime engine that allows developers to use the Javascript language on the server-side to build an application as well as the client-side website which a user interacts with.
