BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by me as part of the curriculum at Lighthouse Labs.

Usage

Install it:

npm install @loganwoolf/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(a, b) : Compares two flat arrays. log true || false
• assertEqual(a, b) : Compares two primitives. log true || false
• assertObjectsEqual(a, b) : Compares two flat objects. log true || false
• countLetters(a) : Returns an object with each unique letter as keys, and occurences of each as value.
• countOnly(a, b) : Takes an array (a) of items, and returns an object with each unique list item as keys, and occurences of each as value. The object is filtered by object (b), containing a number search keys with true value.
• eqArrays(a, b) : Compares two flat arrays. Returns a boolean true if they are identical.
• eqObjects(a, b) : Compares two flat objects. Returns a boolean true if they are identical.
• findKey(a, fn) : Takes an obj (a), searches it for the first key that satisfies a given callback function (fn), and returns that key.
• findKeyByValue(a, b) : Takes an obj (a), searches its values for (b), and returns the parent key.
• flatten(a) : Returns an array that is flattened by one level from (a).
• head(a) : Returns the first item in an array (a).
• letterPositions(a) : Returns an object containing all unique elements of a string (a) as keys, and an array of zero-indexed positions of said elements as values.
• map(a, fn) : Returns a new array containing all of the elements of an input array (a) as modified by a given callback function (fn).
• middle(a) : Returns either the middle or middle two values from a given array (a) as an array.
• tail(a) : Returns all but the first item in an array (a)
• takeUntil(a, fn) : Returns items from the beginning of array (a) until the callback function (fn) condition is met.
• without(a, b) : Returns an array that contains all the elements from an array (a), but with those contained in another array (b) removed.
