@barbmich/lotide v1.0.0

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 @barbmich/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: asserts if two arrays are equal by comparing the element in each same index.
• assertEqual: asserts if two values are strictly equal.
• assertObjectsEqual: asserts if two objects are equals by comparing each key-value pair.
• countLetters: takes a string, outputs an object with the string characters as keys, and their occurrence as value.
• eqArrays: compares two arrays. returns true if they are equal, false otherwise.
• countOnly: takes an array and an object, returns an object that counts how many times an item is found in the array (if 0, it won't be counted).
• eqObjects: compares two objects. returns true if they are equal, false otherwise.
• findKey: takes an object and a callback function. the function scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue: takes an object and a value. the function scans the object and returns the first key which contains the given value.
• flatten: takes an array, returns a 'flattened' version of these arrays, on a single dimension.
• head: takes an array, returns the element in the first index.
• letterPositions: takes a string, returns an object containing all the string characters as keys, and their position as value - spaces are considered but not listed in the keys.
• map: behaves as the map method: takes an array and a callback function, applies callback to each element of the array.
• middle: given an array, returns what's in the middle: 1 element if the array is odd, 2 elements if it is even.
• tail: given an array, returns a new array without its first index.
• takeUntil: takes an array and a value, returns an array made by all elements until such value is encountered (value excluded).
• without: takes two arrays, returns the initial array with elements from the second removed.
