With the development of web pages, JavaScript has become an indispensable part of web development. However, sometimes you may not want to let web pages execute JavaScript. If you are using Google Chrome, this article will tell you how to turn off JavaScript on web pages.

What is JavaScript?

JavaScript is an object-based scripting language, a programming language that can be executed on a web browser. JavaScript can be used to create dynamic web effects and interactive website applications, including playing audio, video, games, and more. It has become so ubiquitous that every website seems to use JavaScript.

Why should you turn off JavaScript?

Sometimes you may need to turn off JavaScript. The following are several possible situations:

  1. When browsing the web, you may encounter some pop-up advertisements. If you turn off JavaScript, these ads will no longer appear.
  2. Improve web page loading speed. When loading a web page, the browser needs to download all JavaScript files and calculate their results locally, which can cause the web page to be slower. If you turn off JavaScript, the webpage will not load JavaScript files, so the webpage will load faster.
  3. Prevent JavaScript attacks. Some websites may exploit JavaScript vulnerabilities to attack your computer. Turning off JavaScript reduces the risk of attacks on your computer.
  4. Improve security. JavaScript can be used to obtain confidential information such as users’ personal information and passwords. Turning off JavaScript protects your privacy and security.

How to turn off JavaScript?

In Google Chrome, turning off JavaScript on web pages is very simple. Here are the specific steps:

  1. First open the Google Chrome browser, click the three horizontal dots in the upper right corner of the browser, and select the "Settings" option.
  2. In the settings page, scroll down and click on the Advanced option.
  3. In the Privacy & Security tab, click the Content Settings option.
  4. In the "Content Settings" page, find the "JavaScript" option and click it.
  5. Click the switch next to the "Allow all sites to run JavaScript" option to turn off JavaScript.
  6. After you turn off JavaScript and navigate away from the settings page, refreshing the page will cause Chrome to reload the page without JavaScript.

Summary

While JavaScript is a very useful technology, it has some drawbacks. If you turn off JavaScript, you can increase web page loading speed, reduce ad pop-ups, and prevent JavaScript attacks, thus improving your online security. At the same time, turning off JavaScript in Google Chrome is also very simple. You only need to follow the above steps to complete.
