Replace last character of string using JavaScript

Question

I have a very small query. I tried using concat, charAt, slice and whatnot but I didn\'t get how to do it.

Here is my string:

var str1 = \"Notion,Data,I         


        

Answer 1

You can do it with regex easily,

var str1 = "Notion,Data,Identity,".replace(/.$/,".")

.$ will match any character at the end of a string.
