: takes in an array and returns the first element in the array.tail(array)
: takes in an array and returns everything except the first element of the array.eqArrays(array1, array2)
: takes in 2 arrays and returns true if the arrays are equal and false otherwise.assertArraysEqual(expected, actual)
: takes in two arrays and prints appropriate message after comparing the two arrays.without(source, itemsToRemove)
: takes in a source array and an itemsToRemove arrays and returns only the items from the source array that are not in the itemsToRemove array.flatten(array)
: takes in an array that contains elements including nested array of elements and returns a flattened version of the array.middle(array)
: takes in an array and returns the middle most element of the array.countOnly(array, object)
