A cool way to use substrings to capitalize the first letter of a name.

subString.js

var fullName = "";
var name;
var firstLetter;

   var fixName = function () {
       
   }


    name = prompt("Enter your first name (all in lower case):");
    firstLetter = name.substring(0, 1);
    name = firstLetter.toUpperCase() + name.substring(1);
    fullName = fullName + " " + name;


    name = prompt("Enter your second name (all in lower case):");
    firstLetter = name.substring(0, 1);
    name = firstLetter.toUpperCase() + name.substring(1);
    fullName = fullName + " " + name;


    console.log("And your full name is:" + fullName);
