It is a dynamic programming language and is used by Web Designers when they want client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that is displayed. It is also being used in server-side programming, game development and the creation of desktop and mobile applications.
JavaScript was traditionally implemented as an interpreted language
but just-in-time compilation
is now performed by recent (post-2012) browsers.
It also has the
ability to insert code into their web page.
JavaScript is commonly placed into an HTML, ASP,
or a similar file and run directly from the web
page to
perform tasks such as printing the time and date, creating a calendar,
or other tasks that are not possible through plain HTML.
