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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Assert that two arrays are equal.
• assertEqual(actual, expected): Assert that two variables are strictly equal.
• assertObjectsEqual(actual, expected): Assert that two objects are equal.
• countLetters(string): Count the letters in a string, ignoring spaces, and return an object with the counts.
• countOnly(array, itemsToCount): Count the elements in an array, given an object with boolean values determining what to count.
• eqArrays(array1, array2): Predicate to test if two arrays are equal.
• eqObjects(object1, object2): Predicate to test if two objects are equal.
• findKey(object, callback): Find the key in an object that satisfies a predicate.
• findKeyByValue(object, value): Find the key in an object that has a given value.
• flatten(array): Flatten an array of arrays.
• head(array): Return the first element of an array.
• letterPositions(string): Given a string, return an object with a key for each included letter, and arrays of indexes as values.
• map(array, callback): Map an array to a new array by applying a callback.
• middle(array): Return the middle of an array (one or two elements based on odd or even lengths).
• tail(array): Return a copy of an array starting from the second element.
• takeUntil(array): Return a copy of an array up until a predicate is satisfied (not inclusive).
• without(source, itemsToRemove): Return a copy of an array with the exclusion of all elements from a second array.
