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.

Install it:

npm install @anthonyrc/lotide

Require it:

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

Call it:

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

• assertArraysEqual(array, array): Print green if two arrays share the same values and red otherwise.
• assertEqual(primitive, primitive): Print green if two primitive values are the same and red otherwise.
• assertObjectsEqual(obejct, object): Print green if two objects keys and values are the same, red otherwise.
• countLetters(string): Return an object with the count of each letter in a string.
• countOnly(array, object): return an object with the count of occurrences of given values that are true.
• eqArrays(array, array): Return true if two arrays share the same values and false otherwise.
• eqObjects(object, object): Return true if two objects keys and values are the same, false otherwise.
• findKey(object, primitive): Given a value find the key of an object.
• findKeyByValue(object, callback): Given a callback that returns a value to some key return the object with that key.
• flatten(array): Recursively place values of an array into an array where the values are primitives.
• letterPositions(string): Return object of all the positions of of all the letters.
