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

You are not passing a string otherwise it would have a replace method. I hope you didnt type function trim(str) { return var.replace(blah); } instead of return str.replace.
