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 @tianhaozhang/lotide
Require it:
const _ = require('@tianhaozhang/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
head(): Returns the first element in a array. -
tail(): Returns every element in a array except the head (first element) of the array. -
middle(): Returns the middle element of a string. -
eqArrays(): Checks if 2 arrays are equal to each other. -
assertEqual(): Checks if the 2 inputed variables are equal. -
assertArraysEqual(): Take in two arrays and console.log an appropriate message to the console. -
assertObjectsEqual(): Take in two objects and console.log an appropriate message to the console. -
countLetters(): Take in a sentence (as a string) and then return a count of each of the letters in that sentence. -
countOnly(): Take in a collection of items and return counts for a specific subset of those items. -
eqObjects(): Take in two objects and returns true or false, based on a perfect match. -
findKey(): 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. -
findKeyByValue(): Takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined. -
letterPositions(): Return all the indices (zero-based positions) in the string where each character is found. -
map(): Take in two arguments, an array to map and a callback function. The map function will return a new array based on the results of the callback function. -
takeUntil(): Keep collecting items from a provided array until the callback provided returns a truthy value. -
without(): Take in a source array and a itemsToRemove array. It should return a new array with only those elements from source that are not present in the itemsToRemove array.
