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 @bbashcode/lotide-flex

Require it:

const _ = require('@bbashcode/lotide-flex');

Call it:

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

Documentation

The following functions are currently implemented:

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

Following functions have been implemented earlier for testing but have been replaced with chai and moca

• assertArraysEqual: a function that takes in 2 arrays and returns true if they are equal and false otherwiseion
• assertEqual: a function that takes in 2 values and returns true if they are equal and false otherwise
• assertObjectsEqual: a function that takes in 2 objects and returns true if they are equal and false otherwise

Current test files are under test subdirectory
