• _.assertArraysEqual(...): assert if two arrays are equal
• _.assertEqual(...): assert if two elements are equal
• _.countLetters(...): count what letter presence and no. of occurence
• _.countOnly(arr, obj): count occurence in array as specificed in obj
• _.eqArrays(arr1, arr2): eval if two arrays are equal
• _.eqObjects(obj1, obj2): eval if two objects are equal
• _.findKey(obj, callback): when callback return true, return key
• _.findKeyByValue(obj, val): return the key of key/val pair from an object
• _.flatten(arr): return a flat array by flattening the input nested array
