A mini clone of the Lodash library.
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.
Install it:
npm install @minzi123/lotide
Require it:
const _ = require('@minzi123/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
-
assertArraysEqual():Take in two arrays and console.log an appropriate message to the console. -
assertEqual(): Compare the two values it takes in and print out a message telling us if they match or not. -
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. -
eqArrays():Takes in two arrays and returns true or false, based on a perfect match. -
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. -
head(): Returns the first item in the array. -
letterPositions():Return all the indices (zero-based positions) in the string where each character is found. -
map(): Will take in two arguments: 1)An array to map, 2)A callback function, and return a new array based on the results of the callback function. -
middle():Take in an array and return the middle-most element(s) of the given array. -
tail():return an array of all elements except first. -
takeUntil():Return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value. -
without(): Return a subset of a given array, removing unwanted elements.
