A mini clone of the Lodash library.

This project was created and published by me as part of my learnings at Lighthouse Labs.

Install it:

npm install @amurrai/lotide

Require it:

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

Call it:

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

The following functions are currently implemented:

function1(...): description

head(arr): returns the first element of an array
tail(arr): returns all elements of an array except from the first

flatten(arr): takes a 2 level array and returns a single level array with the same items
map(arr, callback): returns an array of the results of the callback over each item in arr
takeUntil(arr, callback): returns an array of the callback over each item of arr
without(arr, itemsToRemove): returns an array without the items listed to be removed
findKey(obj, callback): returns the key of callback in obj
findKeyByValue(object, value): returns the key of value in obj
countLetters(str): returns an object with keys for each letter in the string and the value of their respective counts
countOnly(arr1, arr2): returns an object with the items from arr2 as keys and the values equal to the counts of each item in arr1
assertArraysEqual(arr1, arr2): console.log the return of eqArrays
assertEqual(actual, expected): console.log assertion of comparison between actual and expected
assertObjectsEqual(actual, expected): deep comparison between objects actual and expected
eqArrays(arr1, arr2): shallow comparison between arrays arr1 and arr2
