  • Console

The console is one of the most useful tools when debugging JavaScript. When you run JavaScript code, the output will be displayed in the console. You can also run code directly in the console. This is very useful for testing code. The console also provides tools such as executing code, viewing logs, and debugging CSS.

  • Debugger

  • Check network requests

Checking network requests can help you debug your JavaScript code. In 360 Browser, you can view the details of all requests, such as request type, status code, and response headers, in the Network tab. If your code isn't working, inspecting the network requests is a good place to start.
