const results = _.tail([1, 2, 3]) // => [2, 3]

Documentation

The following functions are currently implemented:

• head(array): returns first element of a given array.
• tail(array): returns everything but the first element of a given array.
• middle(array): returns the middle element(s) of an array in a new array.
• assertArraysEqual(array1, array2): compares two arrays and logs to console whether or not they are equal.
• assertEqual(x, y): compares two primitve values and logs to console whether or not they are equal.
• assertObjectsEqual(object1, object2): compares two objects and logs to console whether or not they are equal.
• countLetters(string): returns an object with an occurence count for each character except ' '.
• countOnly(array), object): uses true/false values attached to keys in the input object to return an occurence count for true-flagged keys in the array as an object.
• eqArrays(array1, array2): compares two two arrays and returns whether or not two arrays are the same.
• findKey(object, callback): returns the key in the input object with the value of the callback function.
• findKeyByValue(object, value): returns first key in the input object matching the given value.
• joinList(array): formats single-level arrays into strings.
• letterPositions(string): returns an object containing the indices of all letters in the given string.
• map(array, callback): performs callback function on each element of given array and returns a new array with the values of the callback on the given array.
• takeUntil(array, callback): returns a new array of all elements in given array until element is equal to the return of the callback function provided.
• without(array1, array2): removes elements of array2 from array1 and returns in a new array.
