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 @matheus.chaves/lotide

Require it:

const _ = require('@matheus.chaves/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• function1(assertArraysEqual): function that prints an appropriate message after comparing the two arrays.
• function2(assetEqual): function that takes in 2 values and returns true if they are equal and false otherwise.
• function3(assertObjectsEqual): function that takes in 2 objects and returns true if they are equal and false otherwise.
• function4(countLetters): function that takes in a sentence and returns a count of each of the letters in the sentence.
• function5(countOnly): function that takes in a collection of items and returns a specific subset of those items.
• function6(eqArrays): function that takes in 2 arrays and returns true if the arrays are equal and false otherwise.
• function7(eqObjects): function that takes in 2 objects and return true if they are equal and false otherwise.
• function8(findKey): function that takes in an object and callback and returns the first key that meets the criteria specified in callback.
• function9(findKeyByValue): function that takes in an object and a value and returns the first key that corresponds to that value.
• function10(flatten): function that takes in an array that contains elements including nested array of elements and returns a flattened version of the array.
• function11(head): function that takes in an array and returns the first element in the array
• function12(index): exports all the functions in Lotide as an object.
• function13(letterPositions): function that takes in a string and returns all indices of letter positions in the string.
• function14(map): 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.
• function15(middle): function that takes in an array and returns middle most element of the array.
• function16(tail): function that takes in an array and returns everything except the first element of the array.
• function17(takeUntil): function that takes in an array and callback and returns a slice of the array based on the criteria specified in the callback.
• function18(without): 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.
