What should I do if the js code cannot run after it is formatted?

Solution: 1. Use the JS syntax checking tool to check whether there are syntax errors in the code; 2. Check whether there are missing dependencies in the code and import them correctly; 3. Check whether there are duplicate variable names in the code. And modify the variable name; 4. Check whether the browser-specific API is used in the code, but it is not supported in other browsers, causing it to fail to run.

If your JS code cannot run after formatting, it may be due to the following reasons:

1. Syntax Error: There may be syntax errors in the formatted code, causing it to fail to run. You can use JS syntax checking tools to check your code for syntax errors.

2. Missing dependencies: The formatted code may contain code that relies on other modules or libraries, but the relevant dependencies are not imported, resulting in the inability to run. You can check whether there are missing dependencies in the code and import them correctly.

3. Variable naming conflicts: There may be variable naming conflicts in the formatted code, causing it to fail to run. You can check whether there are duplicate variable names in the code and modify the variable names.

4. Other problems: There may be other problems, such as a browser-specific API used in the code, but it is not supported in other browsers, causing it to fail to run. You can check whether such problems exist in the code and modify the code.

In short, if your JS code cannot run after formatting, you need to check the code carefully and solve the problem. You can use debugging tools to debug, find the problem, and modify the code.
