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 @barbmich/lotide
Require it:
const _ = require('@barbmich/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
assertArraysEqual: asserts if two arrays are equal by comparing the element in each same index.assertEqual: asserts if two values are strictly equal.assertObjectsEqual: asserts if two objects are equals by comparing each key-value pair.countLetters: takes a string, outputs an object with the string characters as keys, and their occurrence as value.eqArrays: compares two arrays. returns true if they are equal, false otherwise.countOnly: takes an array and an object, returns an object that counts how many times an item is found in the array (if 0, it won't be counted).eqObjects: compares two objects. returns true if they are equal, false otherwise.findKey: takes an object and a callback function. the function scans the object and returns the first key for which the callback returns a truthy value.findKeyByValue: takes an object and a value. the function scans the object and returns the first key which contains the given value.flatten: takes an array, returns a 'flattened' version of these arrays, on a single dimension.head: takes an array, returns the element in the first index.letterPositions: takes a string, returns an object containing all the string characters as keys, and their position as value - spaces are considered but not listed in the keys.map: behaves as the map method: takes an array and a callback function, applies callback to each element of the array.middle: given an array, returns what's in the middle: 1 element if the array is odd, 2 elements if it is even.tail: given an array, returns a new array without its first index.takeUntil: takes an array and a value, returns an array made by all elements until such value is encountered (value excluded).without: takes two arrays, returns the initial array with elements from the second removed.
