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 @michaelak/lotide

Require it:

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

Call it:

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

• countOnly(): take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• findKey(): takes in an object and a callback, scans the object and return the first key for which the callback returns a truthy value
• findKeyByValue(): takes in an object and a value, scans the object and return the first key which contains the given value
• letterPositions(): return all the indices (zero-based positions) in the string where each character is found
• map(): description
• takeUntil(): remove items from the array until a condition is satisfied
• without(): return new array, removing unwanted elements from original.
• eqArrays(): check if two arrays are the same
• eqObjects(): check if two objects are the same

• assertEqual():compare two values and check if actual output equals expected
• assertArraysEqual(): compare actual array against expected outcome
• assertObjectsEqual(): compare actual object against expected outcome
