@aiefymenko/lotide v1.0.0

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 @aiefymenko/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function1(head): This function for arrays is to retrieve the first element from the array.
• function2(tail): This function for arrays is to retrieve every element but the first from the array.
• function3(middle): This function returns an array with only the middle element(s) of the provided array.
• function4(assertArraysEqual): This function will help us easily test functions that return arrays.
• function5(assertEqual): This function will help us easily test functions.
• function6(assertObjectsEqual): This function will help us easily test functions that return objects.
• function7(countLetters): The function should take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• function8(countOnly): This function should take in a collection of items and return counts for a specific subset of those items.
• function9(eqArrays): This functions will compare 2 arrays and return true/false if they are equal/!equal.
• function10(eqObjects): This functions will compare 2 objects and return true/false if they are equal/!equal.
• function11(findKey): This function takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• function12(findKeyByValue): This function will help us search for a key on an object where its value matches a given value.
• function13(flatten): This function will take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• function14(letterPositions): This function will return all the indices (zero-based positions) in the string where each character is found.
• function15(map): This function will return a new array based on the results of the callback function.
• function17(takeUntil): This function will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• function17(without): This function will return a subset of a given array, removing unwanted elements.
