Turning off Javascript can greatly improve the loading speed of web pages, especially in low-speed network environments.

Many websites will load advertisements through Javascript. These advertisements will affect the user's browsing experience and even reduce the security of the web page. Turning off Javascript can reduce the interference of advertisements and allow users to focus more on the content of the web page.

Although turning off Javascript can bring some benefits, it will also bring some adverse effects. The following are the main effects:

1. The functions of the web page are limited

After turning off Javascript, some functions in the web page may not work properly, including online video, audio playback, and web games. Some websites do not even support browsers without Javascript enabled, and users will not be able to browse these websites.

2. The layout of the web page has changed

Javascript can help the web page achieve some dynamic effects, such as the expansion and collapse of the navigation bar, the scaling of pictures, etc. Turning off Javascript will affect the display of these effects and sometimes lead to confusing web page layout.

Javascript can help the website detect the user's operation behavior, thereby carrying out some security detection and restrictions. After turning off Javascript, the website may not be able to detect the user's operation behavior, thus increasing some security risks.
