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

This isn't elegant but it's reusable.

term(str, char)

str: string needing proper termination

char: character to terminate string with

var str1 = "Notion,Data,Identity,";

function term(str, char) {
  var xStr = str.substring(0, str.length - 1);
  return xStr + char;
}

console.log(term(str1,'.'))
