: Counts the instances of each letter that appears in a given string.countOnly([...], {...})
: Given an array and an object with boolean values, will count only the truthy values from the object that appear in the array.findKey({...}, callback())
: Returns the first key that returns a truthy value for a given callback function.findKeyByValue({...}, var)
: Returns a key from a given object that corresponds with a given value.letterPositions('...')
: Returns a list of indices for each letter occurence in a given string.map([...], callback())
: Applies a callback function to a given array.takeUntil([...], callback())
: Returns an array up until a point provided by a callback function.without([...], [...])
: Removes items listed in the second array from the first array, returning a new array.assertArraysEqual(...)
: Compare two arrays for a perfect match and outputs a colourful assertion message.assertEqual(var1, var2)
