How do I use a Regex to replace non-alphanumeric characters with white space?

Question

I built a Javascript function to make the first letter uppercase. My issue is that I have some words which are like \"name_something\" and what I want is \"Name Something\".

You can use [\W_] to get rid of characters that are not alphanumeric. Where W represent characters from a-z, A-Z and 0-9

var str = 'this $is a _test@#$%';
str = str.replace(/[\W_]+/g,' ');
console.log(str);

So, to make the words capitalise alongside the replace you can do,

var str = 'this $is a _test@#$%';
str = str.replace(/[\W_]+/g,' ');
var res = str.split(' ').map((s) => s.charAt(0).toUpperCase() + s.substr(1)).join(' ');
console.log(res);
