Documentation

The following functions are currently implemented:

• head(array): takes an array, returns the first element of that array.
• tail(array): takes an array, returns the array without the first element
• eqArrays(array1, array2): takes in two arrays, returns true or false, based on a perfect match.
• assertArraysEqual(array1, array2): takes two arrays, logs message to console asserting their equality.
• middle(array): takes an array, returns the middle-most element(s) of the array.
• without(array1, array2): takes two arrays, returns a copy of array1 with any elements from array2 filtered out from it.
• flatten(array): takes an array of arrays, returns flattened array.
• countOnly(array, object): takes an array and an objects, returns an object listing counts of each array item.
• countLetters(string): takes a string and return a count of each letter in that string.
• letterPositions(array): takes a string, returns indeces for each letter in the string.
• findKeyByValue(object, vale): takes an object and a value, returns the first object key containing the value.
• eqObjects(object1, object2): takes two objects, returns true or false according to match.
• assertObjectsEqual(object1, object2): takes two object, logs message to console according to match.
• map(array, function): takes an array and a function, passes each element through the function and returns the resulting array.
• takeUntil(array, function): takes an array and a function, calls the function on each array element and returns a subset of the array from the first element, until such element that the function returns true.
• findKey(object, function): takes an object and a function, returns the first key on which the function returns true.
