@dfhou29/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 @dfhou29/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): gets the first element of an array.
• middle(array): gets the middle element(s) of an array.
• tail(array): gets all element(s) of an array except for the first element.
• flatten(array): Flattens array a single level deep.
• takeUntil(array, callback): Creates a slice of array with elements taken from the beginning. Elements are taken until callback() returns true.
• without(array, itemsToRemove): Creates an array excluding all given values in itemsToRemove.
• map(array, callback): creates a new array populated with the results of calling callback() on every element in the calling array.
• letterPosition(string): return all the indices in the string where each character is found.
• findKey(object, properties): returns the key of the first element containing the properties.
• findKeyByValue(object, value): gets the associated key of value provided in an object.
• countOnly(object, objectsToCount): return counts for objectsToCount in the object.
• countLetters(string): returns a count of occurrence of each letter in string.
• eqArrays(array1, array2): return true if two arrays are identical.
• eqArraysRecursive(array1, array2): recursive version of eqArrays.
• eqObjects(object1, object2): return true if two objects are identical.
• eqObjectsRecursive(object1, object2): recursive version of eqObjects.
• assertEqual(actual, expected): displays console messages when testing equality of two primitive value.
• assertArraysEqual(actual, expected): displays console messages when testing equality of two arrays. (eqArrays/eqArraysRecursive)
• assertObjectsEqual(actual, expected): displays console messages when testing equality of two Objects. (eqObjects/eqObjectsRecursive)
