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 @gabrichard/lotide
Require it:
const _ = require('@gabrichard/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
head(array)
: find and return the first element of an array.tail(array)
: removes the first element and returns the remainder of the array.middle(array)
: returns the middle index elemenst of a given array.assertEqual(actual, expected)
: a test to compare primitive values to verify that your function is returning the expected outcome.assertArraysEqual(actual, expected)
: a test to compare arrays to verify that your function is returning the expected outcome.assertObjectEqual(actual, expected)
: a test to compare objects to verify that your function is returning the expected outcome.countLetters(string)
: counts the occurence of given letter(s) in a string.countOnly(allItems, itemsToCount)
: takes in a collection of items and return counts for a specific subset of those items.eqArrays(firstArray, secondArray)
: compares two arrays to ensure they are equal.eqObjects(object1, object2)
: compares two objects to ensure they are equal.findKey(object, callback)
: Rakes in an object and a callback. Scans the object and returns the first key for which the callback returns a truthy value.findKeyByValue(object, keyValue)
: finds the key of a given value for an object.letterPositions(sentence)
: returns all the indices in the string where each character is found.map(array, callback)
: performs a callback function on each element of a given array.takeUntil(array, callback)
: return a slice of the array until the callback function returns truewithout(givenArray, removeElements)
: return a subset of agiven array, removing unwanted elements.flatten(array)
: flattens nested arrays into a single array.
