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.

npm install @anniekao/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(...): given two arrays, prints out a string indicating if they are equal
• assertEqual(...): compares two values and prints out a string indicating if they are equal
• assertObjectsEqual(...): given two objects, prints out a string indicating if they are equal
• countLetters(...): given a string, returns an object containing a count of each letter in the string
• countOnly(...): given an array and an object of keys and booleans as values, returns a count of those objects in the array with a value of true in the given object
• eqArrays(...): given two arrays, returns a boolean indicating if they are equal
• eqObjects(...): given two objects, returns a boolean indicating if they are equal
• findKey(...): given an object and a callback, returns the key where the callback evaluates to true
• findKeyByValue(...): given an object and a value, returns the key in the object based on the value
• flatten(...): takes a nested array and returns a new array without nested arrays
• head(...): takes an array and returns the first element of the array
• lettersPositions(...): takes a string and returns an object containing an array for each letter containing their index in the string
• map(...): takes an array and a callback function and returns a new array based on the given callback
• middle(...): takes an array and returns a new array containing the middle element, if the array contains an odd number of items. Otherwise it returns a new array containing the middle two elements (if the array contains an even number of item)
