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 @rreiso/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): returns the first element of the array
• tail(array): returns a new array without the first element
• middle(array): returns a new array with one or two middle element(s)
• assertArraysEqual(array1, array2): asserts if two arrays are equal
• assertEqual(a, b): asserts if two primitive values are equal
• assertObjectsEqual(object1, object2): asserts if two objects are equal
• countLetters(string): returns an object with letters and the number of their occurrences
• countOnly(array, object): input object syntax: {array_el: true}; returns a new object with elements and their occurrences in the array.
• eqArrays(array1, array2): returns true/false
• eqObjects(array1, array2): returns true/false
• findKey(object, callback): returns a key that satisfies the statement in the callback
• findKeyByValue(object, value): returns key if the corresponding value exists in the object
• flatten(array): returns new one-dimentional array
• letterPositions(string): returns an object with letters and their indexes
• map(array, callback): returns a new array with elements that satisfies the statement in the callback
• takeUntil(array, callback): returns new array with elements one by one until the first element that satisfies the statement in the callback
• without(array1, array2): returns a new array with elements from array1 without the elements from the array2
