const _ = require('@jesselap/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): Access the first value of an array.
• tail(array): Access every element of an array except the head.
• middle(array): Return the middle value of an array. If array is length is even, return the two middle values. If array length is less than 3, return empty array.
• assertEqual(actual, expected): Assert whether two values are equal.
• eqArrays(array1, array2): Assert whether two arrays are equal.
• assertArraysEqual(array1, array2): Assert whether two arrays are equal with appropriate message.
• countOnly(allItems, itemsToCount): Takes in a collection of items and returns counts for a specific subset of those items.
• eqObjects(object1, object2): Asserts whether two objects are equal.
• assertObjectsEqual(object1, object2): Asserts whether two objects are equal with appropriate message.
• findKey(object, callback): Returns the first key for which the callback returns a truthy value. If no key is found it returns undefined.
• findKeyByValue(object, value): Searches for a key on an object where its value matches a given value.
• flatten(array): Flattens a nested array into one array.
• letterPosition(sentence): Returns all the indices in the string where each character is found.
• map(array, callback): Returns a new array based on the results of the callback function.
• takeUntil(array, callback): Returns a slice of the array with elements taken from the beginning.
• without(source, itemsToRemove): Return a new array with only those elements from source that are not present in the itemsToRemove array.
• countLetters(string): Takes in a sting and returns a count of each letter.
