Read the hint and I understand, but the | is giving me trouble why do we need to use it? why can you not just use capture like this?
swRegex =(^\s+)(\s+$) ?
let hello = " Hello, World! ";
let wsRegex = /(^\s+)(\s+$)/g; // Change this line
let result = hello.replace(wsRegex,""); // Change this line
console.log(result)
