It loops and then returns the first key which contains the given value. letterPositions(string): It takes in a sentense and return an object with the index of each letter positions map(array, callback): It takes in an array and a callback function where it modifies the input array and returns a new array takeUntil(array, callback): It takes in an array and a callback function where it sets a condition and returns a modified array without(array, itemToRemove): Takes in an array and another array of items to be removed from the original array.
