    What does this .replace(/\s+/g, " ") regular expression do?

    It finds each instance of a double space (or more) in a string and replaces it with a single space.

    Here's an example:

    let string = "     A string    with      many    spaces.    ";
    
    string = string.replace(/\s+/g, " ");
    
    // string = " A string with many spaces. "
    

    Notice that any double, triple, etc. space is converted into a single space.
