There are numerous ways to achieve this, but my preferred method would involve using regex:
arr.map(function(item){ return item.replace(/(.)\1+/g, '*') } )
The map function iterates through the array, providing each item to the function as a parameter one at a time. Since the items are strings, you can invoke the replace function on them. I passed the regular expression as the first argument to the replace function and the replacement (star) as the second argument.
