How to decode a JSFuck script?

Question

I have this code in JavaScript:

[(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+
(![]+[])[!+[]+!+[]]+(!![]+[])[+[]]+(!![]+[])[!+[]+!+[]+!+[]]+
(!![]+[])[+!+[]]]
<         


        

Answer 1

    let elem = yourJSFuck
function decode(elem) {
    return (/\n(.+)/.exec(eval(elem.replace(/\s+/, "").slice(0, -2)))[1]);
}

console.log(decode(elem))

This should work, the source is from this page
