var.replace is not a function

Question

I\'m using the below code to try to trim the string in Javascript but am getting the error mentioned in the title:

function trim(str) {
    return str.replac         


        

Answer 1

Replace wouldn't replace numbers. It replaces strings only.

This should work.

function trim(str) {
    return str.toString().replace(/^\s+|\s+$/g,'');
}

If you only want to trim the string. You can simply use "str.trim()"
