splitGroups.js

// Split String by Identical Characters

// Create a function that splits a string into an array of identical clusters.

// Examples
// splitGroups("555") ➞ ["555"]

// splitGroups("5556667788") ➞ ["555", "666", "77", "88"]

// splitGroups("aaabbbaabbab") ➞ ["aaa", "bbb", "aa", "bb", "a", "b"]

// splitGroups("abbbcc88999&&!!!_") ➞ ["a", "bbb", "cc", "88", "999", "&&", "!!!", "_"]

// Notes
// 1 -  Each cluster should only have one unique character.
// 2 - The resulting array should be in the same order as the input string.
// 3 - Should work with letters, numbers and other characters.
