What is javascript?

JavaScript can be called a multi-paradigm language. It has support for many programming methods. For example, object-oriented, functional and imperative.

This type of programming is not directly related to java. The main syntax of this programming language is the C language, as well as C++.

The basis of browser web pages is HTML code, with which programmers add various interactive elements to the pages.

If javascript is disabled in the browser, interactive elements will not work.

This type of programming language appeared thanks to the joint work of Sun Microsystems and Netscape.

Initially, JavaScript was called LiveScript, but after the Java language became popular among programmers, development companies decided to rename it.

Netscape's marketing department believed that such a name would increase the popularity of the new programming language, which, in fact, happened.

Let us remind you that JavaScript is not directly related to Java. These are completely different languages.

JavaScript Features

Until recently, Java was built into the Google Chrome browser and was installed by default when installing browser software. This script launches applications that work independently of Google Chrome, or created a relationship between the site/application and the browser when the Google Chrome browser does not cope with this task.

But that was earlier. Officially, the company that created Google Chrome announced that starting with version 42 of the browser (presumably this version was released in 2015), Java and Silverlight will be disabled and eliminated from the application software. This is what happened and now the browser supports completely different technologies.

This action is explained by the fact that Java has too often been the cause of browser freezes and crashes. The Google Chrome browser has also stopped using the old API and switched to more modern plugins.
