Javascript

What is Javascript?

Javascript is a scripting language (code) that allows website administrators to apply various effects or changes to the web content as users browse it. Javascript allows uninterrupted use of interactive elements such as, dropdown menus, form validation, and changes to page content without having to load a new page, as a result of interactions. It is also used for website tracking (visitor browsing). Javascript skills are necessary for advertisers wanting to compete and run more efficient and more effective campaigns on Google.
