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 @coding-made-simple/lotide

Require it:

const _ = require('@coding-made-simple/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(...): Will check if two arrays are equal and output a readable comparison.
• assertEqual(...): Will check if two primitive datatype values are equal and output a readable comparison.
• assertObjectsEqual(...): Will check if two objects are equal and output a readable comparison.
• countLetters(...): Will count the amount of occurences of a letter.
• countOnly(...): Will take in a collection of items and return counts for a specific subset of those items. It will only count the items that will be counted must have an attached true value.
• eqArrays(...): Will check if two arrays are equal.
• eqObjects(...): Will check if two objects are equal.
• findKey(...): Takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined. (Description from LHL)
• findKeyByValue(...): Checks for a key on an object where its value matches a given value.
• head(...): Returns the first element in an array.
• letterPositions(...): Returns all indices in a string where each character is found. (Description from LHL)
• map(...): Applies a callback to all elements in an array and return a new array with those new values.
• middle(...): Returns the middle element in an array. If the array length is uneven it will return the two middle values in a new array.
• tail(...): Returns an array with everything except the first element
• takeUntil(...): Returns all values in an array that has passed the callbacks conditional statement
• without(...): Takes in an array and scans the array for specififed values and returns an array without those values.
