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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): assert two arrays are equal
• assertEqual(actual, expected): assert two values are equal
• assertObjectsEqual(actual, expected): assert two objects are equal
• countLetters(string): returns a count of each of the letters in the passed string
• countOnly(allItems, itemsToCount): returns a count for a specific subset of passed items
• eqArrays(array1, array2): compares two arrays and returns a boolean
• eqObjects(object1, object2): compares two objects and returns a boolean
• findKey(object, callback): scans the object and returns the first key for which the callback returns a truthy value
• findKeyByValue(object, value): scans the object and returns the first key which contains the given value
• flatten(array): takes in an array containing elements including nested arrays of elements, and returns a "flattened" version of the array
• head(array): returns the first item in the array
• letterPositions(string): 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
• middle(array): takes in an array and returns the middle-most element(s) of the given array
• tail(array): returns everything except for the first item (head) of the provided array
• takeUntil(array, callback): keeps collecting items from a provided array until the callback provided returns a truthy value
• without(source, itemToRemove): returns a subset of a given array, removing unwanted elements
