Lotide

A mini clone of the Lodash library.

Purpose

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 my learnings at Lighthouse Labs.

Usage

Install it:

npm install @username/lotide

Require it:

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

Call it:

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

Documentation

• assertArraysEqual(...): Checks if two arrays are equal
• assertEqual(...): assert if output of function matches expected output
• assertObjectsEqual(...): asserts to objects are equal
• countLetters(...): count occurances of letters in a string
• countOnly(...): count occurances of an item if it matches an item in an object
• eqArrays(...): Checks if two arrays are equal
• eqObjects(...): checks if both objects have identical keys with identical values.
• findKey(...): return the 1st key for which the callback returns truthy
• findKeyByValue(...): return the 1st key with the value
• head(...): return the 1st element in an array
• letterPositions(...): return all the indices in the string where each character is found
• map(...): return a new array based on the results of the callback function
• middle(...): returns the elements at the middle of an array
• tail(...): returns all elements in an array except the 1st one
• takeUntil(...): return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value
• without(...): return a subset of a given array, removing unwanted elements
