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 @tonyloba/lotide
Require it:
const _ = require('@tonyloba/lotide');
Call it:
const results = _.head([1, 2, 3]) // => [1]
The following functions are currently implemented:
function1(head): function 'head' which returns the first item in the arrayfunction2(middle):function middle takes in an array and return the middle-most element(s) of the given array.function3(map): function 'map' returns a new array based on the results of the callback function.function3(tail): function 'tail' returns the "tail" of an array: everything except for the first item (head) of the provided array.function3(takeUntil): function 'takeUntil' returns a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.function3(without): function 'without' returns a subset of a given array, removing unwanted elements.function3(letterPositions): function letterPositions returns all the indices (zero-based positions) in the string where each character is found.function3(findKey): function '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.function3(findKeyByValue): function '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.function3(eqObjects): function 'eqObjects' takes in two objects and returns true or false, based on a perfect match.function3(eqArrays): function 'eqArrays' takes in two arrays and returns true or false, based on a perfect match.function3(countOnly): function 'countOnly' takes in a collection of items and return counts for a specific subset of those itemsfunction3(countLetters): function 'countLetters' takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
