How to enable javascript in the browser - instructions for all versions

For web pages to function fully and optimally in your browser, javascript must be enabled.

We will tell you what it is and how to enable it in this article.

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

This programming language has an unlimited number of possibilities due to its versatility.

The main aspects of application are mobile applications for smartphones, interactive web pages of sites and services.

Most of the innovation was brought about by the AJAX company joining the project, which provided the features used in the language today.

To save traffic and increase ease of use, JavaScript provides the ability to change pages of sites and services in small parts, unnoticed by the user online.

This does not require turning off the site while editing or adding new information.

Changes happen immediately, without requiring a page refresh or reload.

The JavaScript feature may be disabled for various reasons.

It is possible that the previous user may have intentionally disabled it since it was not required for web browsing. The shutdown could also happen on its own.

Disabling javascript may prevent some links from opening. Below we will look at ways to enable this function in popular browsers.

Conclusion

Today, almost all developers use javascript when creating websites.

Therefore, for websites to function correctly, it is often recommended to enable this feature in your browser.

Javascript is a universal programming language.

With its help, almost all modern websites and services are able to provide animation of GIF images, as well as clickable links and attachments.

JavaScript also allows you to correctly use flash games and applications, for example, VKontakte games.

In other cases (for example, browser games), the presence of a flash player may not be necessary.
