How to split a word in a string and replace letters with different characters in JS-CodePudding

I'm trying to make a function which takes a random word and then splits the word into individual letters, then replace the letters with different characters to hide the word.

This is what I thought of originally, but does not work at all (selectWord and answer are both declared outside of all functions):

function word() {
selectWord = answer.split('').map(letter , " _ ").join('');

document.getElementById('correct-word').innerHTML = selectWord;}

Any input would be greatly appreciated :)

CodePudding user response：

function word() {
    selectWord = answer.split('').map(() => " _ ")).join('');
    
    document.getElementById('correct-word').innerHTML = selectWord;
}

CodePudding user response：

Map takes a function.

selectWord = answer.split('').map(letter=> " _ ").join('');
