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 @japhet-dev/lotide

Require it:

const _ = require('@japhet-dev/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): takes in two arrays and prints if they are equal or not.
• assertEqual(actual, expected): takes in two values and prints if they are strictly equal or not.
• assertObjectsEqual(actual, expected): takes in two objects and prints if they are equal or not.
• countLetters(sentence): takes in a sentence (as a string) and then returns a count of each of the letters in that sentence.
• countOnly(allItems, itemsToCount): takes in a collection of items and returns counts for a specific subset of those items.
• eqArrays(array1, array2): compares two arrays for a perfect match.
• eqObjects(object1, object2): takes in two objects and returns true or false, based on a perfect match.
• findKey(obj, callback): scans the object and return the first key for which the callback returns a truthy value.
• findKeyByValue(object, value): scans the object and returns the first key which contains the given value.
• head(arr): retrieves the first element from the array.
• letterPositions(sentence): returns all the indices (zero-based positions) in the string where each character is found.
• map(array, callback): returns a new array based on the results of the callback function.
• middle(arr): takes in an array and return the middle-most element(s) of the given array.
• tail(arr): retrieves every element except the head (first element) of the array.
• takeUntil(array, callback): keeps collecting items from a provided array until the callback provided returns a truthy value.
• without(source, itemsToRemove): returns a new array with only those elements from source that are not present in the itemsToRemove array.
