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 @dustinader/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(string): Counts letters in givin string and returns an object with keys per letter and values based on how many times they appeared. Example: "strings" = { s:2, t:1, r:1, i:1, n:1, g:1 }
• countOnly(array, object): If key in object exists in array and keys value is true counts every reference in array of every key and returns the result as an object. Example: ["string", "string", "node"], { string: true } = { string: 2 }
• findKey(object, callback): Checks the givin objects values of object where if callback determines the first value it reaches is true then returns its key.
• findKeyByValue(object, string): Checks the givin values of object where the first value it comes across equals the same as the value givin then returns its key.
• head(array): Returns the head of the givin array aka the first element.
• tail(array): Return the entire array except the head/first-element.
• middle(array): Returns the middle element of the array if odd. If the array length is even then returns the 2 elements in the middle of the array.
• map(array, callback): Loops through every item in givin array using a callback function on each and returns the new array.
• flatten(array): Takes every element in a nested array and puts them into a non-nested array.
• letterPositions(array): Takes in a string and returns an object where each letter has an array of possitions where they would be.
• takeUntil(array, callback): Loop through items in array and adding them to a new array until callback is true.
• without(array1, array2): Removes all instances of every item in array1 with array2 items being ones to remove.
