JavaScript Transcriber

Hey there! I'm currently attempting to compile some JavaScript code that I have written in a textarea and get the output of this code. I've tried using the eval() method, but unfortunately, I haven't been able to get the complete response. Can anyone provide guidance on how I can effectively compile JavaScript code from a string and receive the full response similar to what is done on playcode.io?

If you want to experiment with a Function constructor, go ahead

Just keep in mind the possibility of XSS attacks

const code = 'Math.abs(-1)';
const result = new Function('', 'return (' + code + ')')();

console.log(result) // 1

You can also supply arguments when executing the function

const code = 'Math.abs(someNumber)';
const runCode = new Function('someNumber', 'return (' + code + ')');

runCode(-1);
