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 @cheryet/lotide
Require it:
const _ = require('@cheryet/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
head()
: Returns the first element of an array.tail()
: Returns everything but the first element of an array.middle()
: Returns the middle element(s) of an array.assertArraysEqual()
: Strictly compares two arrays and logs result.assertEqual()
: Strictly compares two values and logs result.assertObjectsEqual()
: Strictly compares two objects and logs result.countLetters()
: Counts the letters in a string and returns an object containing what letters appeared x amount of times.countOnly()
: Counts a string and returns a count of a specific subset of that string.eqArrays()
: Strictly compares two arrays and returns true or false based on results.eqObjects()
: Compares two objects and returns true or false based on results.findkey()
: Takes in an object and a callback and returns the first key upon which the callback returns truthy. If no key is found, returns undefined.findKeyByValue()
: Takes in an object and value and returns the first key which contains that value. If no key is found return undefined.flatten()
: Flattens a 2D array.letterPositions()
:Takes in a tring and returns and object with the letter and their respective indices.map()
: Referance MaptakeUntil()
: Takes in an array and a callback. Will return a slice of the array untill the callback provided returns a truthy value.without()
: Takes in a source array and an items to remove array. A new array will be returned with only those elements from the source array that were not present in the items to remove array.
