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 @ranthonym/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(): checks for equality assertion of 2 non-object values
• assertArraysEqual(): checks for equality assertion of 2 arrays
• assertObjectsEqual(): checks for equality assertion of 2 objects
• head() : returns the first index element of an array
• tail() : returns array without the head element
• middle() : returns the middle index elements of an array
• eqArrays() : compares 2 arrays and returns a boolean value
• eqObjects() : compares 2 objects and returns a boolean value
• takeUntil() : take in source value and array, returns subset array with all values up to first instance of source value
• without() : take in source values and array, returns subset array without those source values
• map() : takes in a function argument and returns a mutated array
• letterPositions() : return all the indices (zero-based positions) in the string where each character is found.
• flatten() : takes in an array of arrays and returns a "flattened" version of the array.
• findKey() : takes in an object and a callback and returns the first key for which the callback returns a truthy value.
• findKeyByValue() : takes in an object and a value and returns the first key which contains the given value.
• countOnly() : takes in a collection of string items and returns counts for a specific subset of those items.
• countLetters() : takes in a sentence (as a string) and then returns a count of each of the letters in that sentence.
