Meaning of javascript (what is it, concept and definition)

What is Javascript:

Javascript (JS) is a standard web programming language for the interaction and automation of web pages and web applications. In them, JavaScript is responsible for the dynamics in changing colors, appearance of dialog boxes and validation of forms, among other examples.

Javascript is a language used by web developers and considered "client-side" programming. This means that the code or script entered in the web pages are executed by the browsers by the user. In this sense, Javascript has become a standard language because it is compatible with all current browsers, such as Google Chrome, Firefox, Explorer, among others.

The objective of Javascript is to improve the user experience through the creation of a common language for the dynamic elements and contents of dynamic contents of all the applications that we know, from the calculator, the calendar and the phone contacts to the Rich applications of social networks such as Facebook, Twitter, Outlook and Google.

When browsing some web pages or applications, the option “Enable Javascript” usually appears. This option indicates that there are some functions with Javascript language that will be executed on the web page that we want to access. If Javascript is not enabled, some dynamics of the original design may not appear.

Javascript Origin

Javascript was born as the standard language of the Netscape browser that was discontinued after being defeated in the so-called Browser War in the late 1990s. Today, Javascript is used in all browsers. To learn this language, it is recommended to have knowledge of HTML and some CSS bases.

Javascript Libraries

To program more complex Javascript codes there are Javascript libraries. The best known and with the basic functions is known as Jquery. There are other Javascript libraries that allow, for example, compatible old codes or simplify complex functions such as AngularJS, Polymer, React, among others.
