Documentation

The following functions are currently implemented:

• assertArraysEqual(): checks if 2 arrays match or not.
• assertEqual(): checks if 2 primitives values are equal.
• assertObjectsEqual(): checks if 2 objects are equal.
• head(): returns the first element in an array.
• tail(): returns every element except the head (first element) of the array.
• middle(): returns an array with the middle elements of another array.
• countLetters(): counts the number of occurrences of each letter in a string.
• countOnly(): takes in an array and an object as arguments, and counts a specific subset of that array and ignoring the rest, depending on what's specified in object.
• eqArrays(): to compare 2 arrays.
• eqObjects(): to compare 2 objects.
• findKey(): takes in an object and a callback function as arguments. It checks the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue(): takes in an object and a value function as arguments. It checks the object and returns the first key which contains the given value.
• flatten(): description
• function1(...): takes an array of nested arrays and returns a single-level array.
• letterPositions(): takes in a string and return an object with the letters and the indices where they were found.
• map(): returns an array with the first letter of every string from the input array.
• takeUntil(): returns a "slice of the array with elements taken from the beginning.
• without(): takes in an array and an another array of items to remove as arguments. It returns a new array where the items to remove were removed.
