What are the common errors when running a Javascript file in the terminal?

-SyntaxError: The most common error when running JS code, a SyntaxError occurs when the JS interpreter encounters code that it cannot understand. This can be due to incorrect syntax, or an unsupported feature being used.
-ReferenceError: A ReferenceError occurs when the JS interpreter encounters a reference to an undefined variable.
-TypeError: A TypeError occurs when a value is used in an unexpected way. For example, trying to use a string as a number, or calling a function that does not exist.

How to troubleshoot errors when running a Javascript file in the terminal?

If you’re having trouble running a Javascript file in the terminal, there are a few things you can try to troubleshoot the problem.

First, make sure that you are in the correct directory when you try to run the file. If you’re not sure which directory you’re in, you can use the ‘pwd’ command to print the current working directory.

Next, check that the file exists in the current directory by using the ‘ls’ command to list all of the files and directories in the current working directory. If the file you’re trying to run doesn’t appear in the list, it’s likely that it’s not in the current directory.

If the file does exist but you’re still having trouble running it, make sure that it has executable permissions by using the ‘ls -l’ command to list all files and directories in the current working directory with their permissions. Executable files will have an ‘x’ in the permissions column. If the file doesn’t have executable permissions, you can use the ‘chmod +x’ command to add executable permissions.

Finally, if all else fails, try running your Javascript file with a different interpreter by using a shebang line at the top of your code. For example, if your code is compatible with both Node.js and Rhino, you could use a shebang line like this:

#!/usr/bin/env node
or
#!/usr/bin/env rhino
