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 @philteigne/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): Returns first element in a given array.
• tail(array): Returns all but first element in a given array.
• middle(array): Returns the middle element in a given array of at least length 3. If the array has an equal number of elements it will return both middle elements.
• map(array, callback): Returns array with callback specified adaptations made to each element of the inputted array.
• assertArraysEqual(array1, array2): Returns a true assertion if the two given arrays are identical, and a false assertion if they are not.
• assertEqual(value1, value2): Returns a true assertion if the two given values are identical, and a false assertion if they are not.
• assertObjectsEqual(object1, object2): Returns a true assertion if the two given objects are identical, and a false assertion if they are not.
• countLetters(string): Returns an object containing the counts of instances of letters in the given string.
• countOnly(array, object): Return an object containing counts from the given array, of everything that the given object listed.
• eqArrays(array1, array2): Returns true if the two given arrays are identical, return false if they are not.
• eqObjects(object1, object2): Return true if the two given objects are identical, return false if they are not.
• findKey(object, callback): Returns the first instance that satisfies callback in the given object.
• findKeyByValue(object, value): Returns the first key in the provided object that contains the input value.
• flatten(array): Returns a 1 dimensional array given an array with nested elements.
• letterPositions(string): Returns an object that lists the index location of all letters in the input sentence.
• takeUntil(array, callback): Returns all characters in a string up until the callbacks conditions are met.
• without(array1, array2): Returns an array with all values listed in the filter array (array2), removed.
