@brianguyen97/lotide v1.0.1

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 @brianguyen97/LOTIDE

Require it:

const _ = require('@brianguyen97/LOTIDE');

Call it:

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

Documentation

The following functions are currently implemented:

• function1(countLetters): Pass in a string, returns an object showing how many times each letter appears in the string

• function2(countOnly): countOnly will be given an array and an object. It will return an object containing counts of everything that the input object listed.

• function3(findKey): Takes in an object and a callback. It scans the object and returns the first key for which the callback returns a truthy value. If no key is found, undefined is returned

• function4(findKeyByValue): Takes in an object and a value. It scans the object and returns the first key which contains the given value. If no key with that given value is found, then it should return undefined.

• function5(flatten): Flatten takes in an array containing elements including nested arrays of elements, and returns a "flattened" version, removed the nested arrays.

• function6(head): Takes in an array and returns the first element

• function7(letterPositions): Returns all the indicies in the string where each character is found as an object

• function8(map): Own version of map, iterates over an array, do something to it, and return a new array.

• function9(middle): Returns the most middle element of an array, one element if there is an odd amount, two if it's even. Minimum of 3 elements

• function10(tail): Takes in an array, returns a new array with everything besides the first element, the "tail".

• function11(takeUntil): Takes in an array and a callback, the function will return a slice of the array, starting from element 0, and it'll keep going until the callback returns a truthy value.

• function12(without): Takes in 2 arrays, and return everything from the first array, excluding the elements in the second array.

• function13(assertArraysEqual): Takes in 2 arrays, compare them to see if they're equal.

• function14(assertEqual): Compares 2 values to see if they're equal

• function15(assertObjectsEqual): Compares 2 objects to see if they're equal.

• function16(eqArrays): Compares 2 arrays to see if they're equal.

• function17(eqObjects): Compares 2 objects to see if they're equal. Returns true or false.
