I have to write several lines of code to remove delimiters from a string. Is there a more efficient way to remove all delimiters? Thanks.

    str = str.toLowerCase();
    str = str.replace(/ /g,'');
    str = str.replace(/\*/g, '');
    str = str.replace(/_/g, '');
    str = str.replace(/#/g, '');
    //etc....

• 1 You can't just remove delimiters this way, they are paired and possibly escaped as a literal. – user557597 Commented Jun 28, 2017 at 18:37

Use character class:

str = str.toLowerCase().replace(/[ *_#]/g, '');
