cwd doesn't execute on the current working directory

Question

In my understanding from How to run shell script file using nodejs?, this code should give me the current directory of the js file:

exec('dir', {cwd: "." }, (error, stdout, stderr) => {
            console.log(stdout);
            console.log(stderr);
            if (error !== null) {
                console.log(`exec error: ${error}`);
            }
        }); 

But the result is another directory. How to fix this? I'm on Windows 11 Home, and use esbuild to bundle ts to js.
