var removeCharacter="abab";

To replace characters at specific index in above String follow below steps.

var index=2;
var replaceAbleCharacter='x';
removeCharacter=removeCharacter.substring(0,index)+replaceAbleCharacter+removeCharacter.substring(index+1,removeCharacter.length);

abxb

A String in javascript is an immutable object.
So modified data is stored in new block of memory.
