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 @eruzai/lotide

Require it:

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

Call it:

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

• head(...): returns the head (first element) of an array
• tail(...): returns the tail (every element following the head) of an array
• middle(...): returns the middle-most element(s) of an array
• assertArraysEqual(...): takes two arrays, compares them for equality, and outputs an appropriate message to the console
• assertEqual(...): takes two values, compares them for equality, and outputs an appropriate message to the console
• assertObjectsEqual(...): returns true if both objects have identical keys with identical values
• countLetters(...): return a count of each letter in a given string
• countOnly(...): returns an object with counts of all specified items within source object given by array.
• eqArrays(...): takes two arrays and returns true or false, based on a perfect match
• eqObjects(...): returns true if both objects have identical keys with identical values
• findKey(...): searches an objects keys and performs callback function on each, returns first key that resolves callback
• findKeyByValue(...): scans an object to return the first key containing the given value
• flatten(...): takes an array or nested arrays of elements, and returns a "flattened" version of the array
• letterPositions(...): accepts a string and returns an object containing each letter and all of it's index locations
• map(...): creates a new array after resolving callback function on each element
• takeUntil(...): creates a new array with elements up to the callback resolution
• without(...): return a subset of a given array, removing unwanted elements
