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 @chonie1/lotide

Require it:

const _ = require('@chonie1/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(str): counts the number of occurences of each character given a string
• countOnly(allitems, itemsToCount): given an allItems array, and an itemsToCount object, returns an object with the value true/false if the item in itemsToCount is present in allItems
• eqArrays(arr1, arr2): returns true if two arrays are equal else false
• eqObjects(obj1, obj2): returns true if two objects are equal else false
• findKey(obj, callback): returns a key in the obj given a callback function with a conditional
• findKeyByValue(obj, val): returns the first key in the obj that matches the val input
• flatten(arr): flattens a nested array
• head(arr): returns the first element of the array
• letterPositions(str): returns an array of indices for each char in the string
• map(arr, callback): changes the array given a callback function
• middle(arr): returns the middle element of the array (returns an array of two numbers if the input array length is even)
• tail(arr): removes the first element of the array
• tailUntil(arr, callback): returns part of the array depending on the callback conditional
• without(source, itemsToRemove): removes items in source given an itemsToRemove array
