@sharleenb/lotide v1.0.3

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. It is meant to be a clone of the Lodash library, writing similar utility functions that can go a long way in future code writing.

Usage

Install it:

npm install @sharleenb/lotide

Require it:

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

Call it:

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

• head: function takes in array and returns first element of array
• tail: function takes in array and returns everything except the first element of array
• middle: function takes in array and returns middle most element(s) of array
• countLetters: function that takes in a sentence and returns a count of each of the letters in the sentence
• countOnly: function that takes in a collection of items and returns a specific subset of those items
• eqArrays: function takes in 2 arrays and returns true if they are equal and false otherwise
• eqObjects: function takes in 2 objects and returns true if they are equal and false otherwise
• findKey: return corresponding key for passed in value that is an object
• findKeyByValue: function takes in object and value and returns the first key that corresponds to that value
• flatten: function that takes in an array that contains elements including nested arrays and returns a flattened verison of the array
• letterPositions: function that takes in a string and returns all indices of letter positions in the string
• map: function takes in array and callback and returns a new array based on the results of the callback on each item in the array
• takeUntil: function takes in an array and callback and returns a slice of the array based on the criteria specified in the callback
• without: function takes in a source array and itemsToRemove array and returns only the items from the source array that are not in the itemsToRemove array
• assertArraysEqual: function takes in 2 arrays and returns true if they are equal and false otherwise
• assertEqual: function takes in 2 values and returns true if they are equal and false otherwise
