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 @mahsa1990a/lotide
Require it:
const _ = require('@mahsa1990a/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
function(assertArraysEqual): Asserts whether two arrays are equal -
function(assertEqual): Asserts whether two primitive values are equal -
function(asserObjectEqual): Asserts whether two objects are equal -
function(countLetters): Returns an object where each unique character encountered in a given string is a key and the value for that property should be the number of occurrences for that character -
function(countOnly): Given an array and an object, it will return an object containing counts of everything that the input object listed and was contained in the array as well -
function(eqArrays): Compares the data of two arrays to check if they are equal to each other -
function(eqObjects): Compares the data of two objects to check if they are equal to each other -
function(findKey): Takes an object and a callback and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined -
function(findKeyByValue): Takes an object and a value and returns the first key which contains the given value. If no key with that given value is found, it returns undefined. -
function(head): It returns first index in array -
function(letterPositions): Returns an object containing each characters as keys and as values all the indices in the string where each character is found. -
function(map): Returns a new array based on the results of the callback function. -
function(middle): It returns middle number in array -
function(tail): It returns array without index0 means first value -
function(takeUntil): Returns a "slice of the array with elements taken from the beginning." It should keep going until the callback returns a truthy value. -
function(without): Takes an array and an itemsToRemove array. It should return a new array with only the elements from source that are not present in the itemsToRemove array.
