Convert JSFuck to normal JS

Many of you already know JSFuck. For those who don't, it's a script that basically turns any JavaScript code into something written using only []()!+.

• Input: A string with valid JSFuck code.
• Output: A string with the regular JavaScript code that has been previously JSFucked to generate the input.

Answer:

Run in console of your browser

alert(/.+(?=\n})/.exec(eval(prompt().slice(0,-2))))
