@raemekhatib/lotide v1.0.0

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 @raemekhatib/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head([array]): passes in an array, and returns the first item that is in the index of the array 0;
• tail([array]): take in an array, and returns everything after index 0;
• middle([array]): takes in an array, and return the middle value if there is an odd number of values then it returns a single value, if there is an even number of values it returns the 2 middle values. However returns empty string if there is 0-2 values;
• countLetters("string"): takes in a string or sentence, and returns the letters encountered, as well as number of occurances of each letter;
• countOnly(allItems, itemsToCount): take in two arguements, the first arguement is an array of strings that we need to look through, and the second arguement is an object specifying what to count ( ie , a list of names, and checking if that "name" occurs more than once, and returns the name and how many occurances )
• eqArrays([Array1],[Array2]): takes in 2 arrays, and checks to see if Array1 = Array2, and returns true or false
• eqObjects({Object1}, {Object2}): takes in 2 objects and scans through the keys to confirm if they are equal, returns a true or false value
• findKey({object}, callback): scans through object keys and return the first true value, returns key for given value through function (action) parameter.
• findKeyByValue({object}, value): scans through an object key-value pair search for the matching "value" and returns the key
• letterPositions("string"): takes in a string or sentence, and outputs the index of the letter occurances (the L in "Hello" => 2, 3)
• map([array], callback): takes in an array and callback function, and returns a new modeified array based on action taken (ie 1,2 *2 will return 2,4)
• takeUntil([array], callback): takes in an array and callback function, and pushes items into the array until the "break" value ( ie will push words from a sentence 1, 2, 5, 7, 2, -1, 2, 4, 5 until x < 0 so it stops at -1, returns 1, 2, 5, 7, 2)
• without(items, itemsToRemove): takes in 2 values, the original string, and the stuff you want to remove ( ie input = 1,2,3 and remove: 1 so the output will be 2,3)
