Lotide

A mini clone of the Lodash library.

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.

Install it:

npm install @dpletzke/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

(head): returns first element of an array
(tail): returns last element of an array
(middle): returns the middle element or pair of elements
(assertArraysEqual): prints to console if arrays are deep equal
(assertEqual): prints to console if values are strict equal
(assertObjectsEqual): prints to console if objects are deep equal
(countLetters): counts a passed character in a string
(countOnly): counts a passed item in a array
(eqArrays): returns true if arrays are deep equal
(eqObjects): returns true if objects are deep equal
(findKey): returns key who's value returns true when passed into callback
(findKeyByValue): returns key of passed value
(flatten): returns 1d array of passed many dimensional array
(letterPositions): returns an object of key: value pairs of all characters in a string where the value is an array of the indexes of that character
