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 @james-truong as part of my learnings at Lighthouse Labs.
Usage
Install it:
npm install @james-truong/lotide
Require it:
const _ = require('@james-truong/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(arr1, arr2): Logs a message to show whether 2 arrays match. -
assertEqual(x,y): Logs a message to show whether 2 primary objects match. -
assertObjectsEqual(Obj1, Obj2): Logs a message to show whether 2 objects match. -
countLetters(string): returns the count of each letter of the string with an Object format. -
countOnly(array, itemstoLookfor): searches through the array and looks for itemsToLookFor. Returns an object with the new counts. -
eqObjects(obj1, obj2): compares 2 objects and returns true if they're equal. -
eqArrays(arr1,arr2): compare 2 arrays and return true if they're equal. -
findKey(obj1, callback): returns the first key which matches the value which is given by the callback. -
findKeyByValue(object, value): returns the first key which matches the value. (This is with no callback function). -
flatten(array): Takes in a potentially nested array and spreads it to a single-nested array. -
head(array): returns the front of the array. -
letterPositions(sentence): returns an object that contains the letters (key) and index positions (value) of the sentence -
map(array, callback): takes in two arguments 1) array to map and 2) callback function (when predicate is met) should return the altered array -
middle(array): returns a new array with the middle index value/s of the original array -
tail(array): returns a new array without the first index value of the original array -
takeUntil(array, callback): takes a slice of an array with index values taken from the beginning until callback/predicate returns a truthy value -
without(source, itemsToRemove): returns an array without the specified items
