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 @timjquigg/lotide
Require it:
const _ = require('@timjquigg/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(actual, expected)
: Compares 2 arrays and confirms if they are deeply equal -
assertEqual(actual, expected)
: Compares 2 primitive values and confirms if they are equal -
assertObjectsEqual(actual, expected)
: Compares 2 objects and confirms if they are deeply equal -
countLetters(str)
: Accepts a string input and produces an object with the total occurances of each letter in the string -
countOnly(allItems, itemsToCount)
: Accepts an array of values and produces an object with the total occurances of items that appear initemsToCount
-
eqArrays(arrOne, arrTwo)
: Accepts two arrays and does a deep equals comparison -
eqObjects(object1, object2)
: Accepts two objects and does a deep equals comparison -
findKey(obj, callback)
: Returns the key of an object who's value meets the criteria provided in the callback function -
findKeyByValue(obj, targetValue)
: Returns the key of an object who's value is the target value -
flatten(arr)
: Accepts a nested array and returns of flattened array -
head(input)
: Accepts and array and returns the first element of the array -
letterPositions(sentence)
: Accepts a string and returns an object with each letter in the string as keys and values being arrays of the index of each occurance of the letter -
map(arr, callback)
: is an implimentation of the built-in Array.Prototype.map() function -
middle(arr)
: Accepts an array as input and returns the middle element(s) -
tail(input)
: Accepts an array as input and returns a new array with the first element removed -
takeUntil(array, callback)
: Accepts an array as input and returns a new array containing all of the elements up until the conditions of the callback function are met -
without(source, itemsToRemove)
: Accepts an array as input and returns a new copy with the items initemsToRemove
removed
