Remove commas from regex using JavaScript

Question

I don't know how to remove the commas when result is displayed on my website.

let regex = /\W/g;
let string = "How are you today?";
let string2 = "48%"
let result = string.match(regex);
let result2 = string2.match(regex);

document.getElementById("header").innerHTML = result;
document.getElementById("head").innerHTML = result2;

<p id="header"></p>
<p id="head"></p>

Well the result of your match is [' ', ' ', ' ', '?'] so what are you expecting??? You expecting to see whitespace in the HTML? What were you thinking you were going to see? You are setting innerHTML to an array which will use toString() — epascarello

Because you're matching all the non word chars \W so change to \w — IT goldman

innerHTML expects a string. You are setting it to an array. So the engine runs toString() on the array which returns all the indexes separated by a comma.

If you want to control how it is outputted, you need to use the join() method.

No character would be result.join('')
