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 @amrinder.singh/lotide
Require it:
const _ = require('@amrinder.singh/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
assertArraysEqual(array1, array2)
: Assertion test for eqArrays function.assertEqual(actual, expected)
: Assertion test which compares actual input and expected input. Will not work with objects.assertObjectsEqual(object1, object2)
: Assertion test for eqObjects function.countLetters(string)
: Takes in a sentence or a string and returns an object containing all the letters and their count.countOnly(array, object)
: Iterates over the array and returns only keys which have the value true in the object.eqArrays(array1, array2)
: Compares two arrays and returns true if they contain the same values.eqObjects(object1, object2)
: Compares two objects and returns true if they have the same key/values.findKey(object, callback)
: Returns the first key in an object for which the callback returns a truthy value.findKeyByValue(object, value)
: Returns the key in an object, according to the value.flatten(array)
: Can take nested arrays as parameters and returns a single array with all elements.head(array)
: Returns the first element in an array.letterPositions(string)
: Takes in a word or sentence and returns an object which contains each letter and an array of letter positions based on index.map(array, callback)
: Returns an array with the callback function applied to each element.middle(array)
: Returns the middle value or values of an array.tail(array)
: Returns an array without its first element.takeUntil(array, callback)
: Iterates over the array until the conditions of the callback return a truthy value, and returns new array with all elements until.without(source, itemsToRemove)
: Removes array of items from source array and returns new array.
