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 @lma2023/lotide

Require it:

const _ = require('@lma2023/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: akes in 2 arrays and returns true if they are equal and false otherwise.
• assertEqual: takes in 2 values and returns true if they are equal and false otherwise.
• assertObjectsEqual: takes in 2 objects and returns true if they are equal and false otherwise.
• countLetters: returns a count of each of the letters in the sentence.
• countOnly: returns a specific subset of the collection of items.
• eqArrays: takes in 2 arrays and returns true if the arrays are equal and false otherwise.
• eqObjects: takes in 2 objects and return true if they are equal and false otherwise.
• findKey: takes in an object and callback and returns the first key that meets the criteria specified in callback.
• flatten: takes in an array that contains elements including nested array of elements and returns a flattened version of the array.
• head: returns the first element of input array.
• letterPositions: takes in a string and returns all indices of letter positions in the string.
• map: 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: takes in an array and returns middle most element of the array.
• tail: takes in an array and returns tail elements except the first element of the array.
• takeUntil: takes in an array and callback and returns a slice of the array based on the criteria specified in the callback.
• without: 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.
