Documentation

The following functions are currently implemented:

• head(array): A function for arrays to retrieve the first element from the array.
• tail(array)): A function to retrieve every element except the head (first element) of the array.
• middle(array): A function to return an array with only the middle element(s) of the provided array.
• countLetters(string): The function takes in a sentence (as a string) and then returns a count of each of the letters in that sentence.
• countOnly(array, object): Given an array and an object, it will return an object containing counts of everything that the input object listed.
• findKey(object, callback): A function which takes in an object and a callback. It scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue(object, value): It will help us search for a key on an object where its value matches a given value.
• flatten(array): Given an array with other arrays inside, this function can flatten it into a single-level array.
• letterPositions(string): A function which returns all the indices (zero-based positions) in the string where each character is found.
• map(array, callback): A function that takes an array and a callback function. It will return a new array based on the results of the callback function.
• takeUntil(array, callback): The function returns a "slice of the array with elements taken from the beginning." It keeps going until the callback/predicate returns a truthy value.
• without(array, itemsToRemove): This function takes in a source array and a itemsToRemove array. It returns a new array with only those elements from source that are not present in the itemsToRemove array.
