How does shelljs.exit work?

shelljs.exit is a function provided by the ShellJS library that can be used to exit the current process with a specified exit code.

When called, shelljs.exit takes an optional numeric exit code as its argument, which defaults to zero if not provided. The function then terminates the current process with the specified exit code, causing any code executing after the call to shelljs.exit to be skipped.

Here is an example of using shelljs.exit to exit a script with a non-zero exit code:

javascript
const shell = require('shelljs');

if (!shell.which('git')) {
  console.error('Git not found!');
  shell.exit(1);
}

// ... more code here ...

In this example, we use the shell.which method to check if the Git command-line tool is installed on the user's system. If it is not, we log an error message and call shell.exit(1) to exit the script with an exit code of 1, indicating that an error occurred.

By using shelljs.exit and other methods provided by the ShellJS library, developers can write shell-like scripts in JavaScript that can interact with the file system and command-line tools, making it a valuable tool for many scripting tasks.
