With the rapid development of Internet technology, JavaScript required for web applications has gradually become an important part of design and development.

If this page contains JavaScript code, the browser will execute the code and convert it into relevant website functions and dynamic effects. This process makes the website more interesting and interactive.

Why can’t the browser turn on JavaScript?

Although JavaScript is a key component of web applications, there are situations where browsers may not be able to open JavaScript properly. The following are several common reasons why browsers cannot open JavaScript:
