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 @lupitareyess/lotide
Require it:
const _ = require('@lupitareyess/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(arr1, arr2): Checks if inputted arrays are equal and prints assertions. -
assertEqual(actual, expected): Reports if actual input matches expected input. Returns assertion passed if there is a match, and returns failed if it does not match. -
assertObjectsEqual(obj1, obj2): Checls if inputted objects are equal. -
countLetters(str): Takes in string of letters and returns the count of each letter in the string. -
countOnly(allItems, itemsToCount): Returns object with the count of items of interest. -
eqArrays(arr1, arr2): Checks if inputted arrays are equal. -
eqObjects(obj1, obj2): Checks equality of objects by looping through key:value pairs. -
findKey(obj, callback): Scans object and returns the first key for which the callback statement returns a truthy value. -
findKeyByValue(obj, value): Scans object and returns the first key which contains the given value. -
head(arr): Returns first element in array. -
letterPositions(str): Returns all the indixes in the string where each charcter is found. -
map(arr, callback): Returns a new array based on results of the callback function. -
middle(arr): Return middle element(s) in array. -
tail(arr): Returns all elements in an array, except the first element. -
takeUntil(arr, callback): Collects items from array until the callback provides returns a truthy value. -
without(source, itemsToRemove): Returns a subset of a given array, removing unwanted elements. Does not alter original array.
