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 @jordanbjohnson/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented: 'const results = _.head([1,2]) // => 1'

• head(passes array): passes in an array, and returns the first item in that array

• tail(array): takes in an array and returns everything after element 0 [1,2,2,2,3] return [2,2,2,3]

• middle(array): takes in an array and returns the middle value if odd, and the 2 middle values if even, and if 0 - 2 values, comes back empty [1,2,3,4,5] return [3]

• countLetters(string): input 1 sentence and return an object that has the letter encountered and how many occurences of those letters [assist] {a: 1, s: 3,
  i: 1, t: 1 }

• `countOnly(array, strings): counts the occurances of strings passed in and how many times they were passed in in a list of names, ie: list of names, how many occurances of those names [assist] {a: 1, s: 3,
  i: 1, t: 1 }

• eqArrays([array1], [array2]): takes in an compares the values of two different arrays [1,2,3,4] [1,2,3,4] returns true

• eqObjects(obj1, obj2): confirms if two object arguments (object1, object2) are indentical, will return true or false value. ----Example---- Function: eqObjects({ a: "1", b: "2" }, { b: "2", a: "1" }) Return: true

• findKey(object): scan and return first key which the callback returns truthy, if nothing found, return undefined {key1: 1, key2: 2 key3: 3 } (key2) return truthy at key2

• findKey(obj, action): returns key for given value through function (action) parameter. ----Example---- Function: findKey({ "Blue Hill": { stars: 1 }, "Akaleri": { stars: 3 }, "Noma": { stars: 2 }, "elBulli": { stars: 3 }, "Ora": { stars: 2 }, "Akelarre": { stars: 3 } }, x => x.stars === 2) Returns: "Noma"

• letterPositions(passes string): function to return the original position of the letter in the string (the L in :Hello" => [2,3])

• map(arrays): map() is main function that takes 2 arguments, one an array and other with a callback function. when the map is called, are calling our callback function i.e. regularFun("ground"); ( [1,2]) *2 ([2,4 ])

• takeUntil(arrays): takes in an array and pushes items into the array until the break value ie: const data2 = ["I've", "been", "to", "Hollywood", ",", "I've", "been", "to", "Redwood"]; argument "," return: "I've", "been", "to", "Hollywood"
