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 @davique/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: compares two arrays and asserts if the are the same assertArraysEqual([1, 2, 3], [1, 2, 3]) // => ✅✅✅ Assertion Passed: [1,2,3] is equal to [1,2,3]
• assertEqual: compares two values and asserts if they are the same assertEqual(1, 1) // => ✅✅✅ Assertion Passed: 1 === 1
• assertObjectsEqual: compares two arrays and asserts if the are the same ✅✅✅ Assertion Passed: { a: 1, b: 2 } is equal to { a: 1, b: 2 }
• countLetters: returns how many times each letter appears in a string _.countLetters('Hola') // => { H: 1, o: 1, l: 1, a: 1 }
• countOnly: takes an array and a object with a subset of those items as keys and a boolean as a value and returns counts of the items that were truty
• eqArrays: function that compares two arrays, returns true or false
• eqObjects: function that compares two objects, returns true or false
• findKey: function that evaluates an object and returns the value for the truty callback function
• findKeyByValue: looks inside an object for the value given and returns the key where that value is
• flatten: converts a nested array into a single alyer array
• head: returns the first item of and array _.head([1, 2, 3]) // => 1
• letterPositions: given a string it returns the position or index of the characters
• map: a function that creates a new array with the results of calling a callback function on every element from a given array
• middle: returns the middle item of and array if odd number of elements, or the two middle items if and even number of elements _.middle([1, 2, 3]) // => [2]
• tail: removes the first item of an array and returns the remainder items _.tail([1, 2, 3]) // => [2, 3]
• takeUntil: given an array and an item of that array it return a new array with the elements of the original array until it finds the given item
• without: returns a new array without the element entered as an argument
