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 @ahabes/lotide
Require it:
const _ = require('@ahabes/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
The following functions are currently implemented:
assertEqual(actual, expected)
: Compares the two values and checks if they match or not.assertArraysEqual(arr1, arr2)
: Given two arrays, the function asserts if they are equal.assertObjectsEqual(obj1, obj2)
: Compares the two objects and checks if they match or not.countOnly(allItems, itemsToCount)
: Given an array and an object. It will return an object containing counts of everything that the input object listed.countLetters(sentence)
: Takes in a sentence (as a string) and then return a count of each of the letters in that sentencefindKeyByValue(obj, key)
: Takes in an object and a value. It should scan the object and return the first key which contains the given value.flatten(array)
: Takes a nested array and flattens it into one-level array.head(array)
: Returns the first element of the array.letterPositions(sentence)
: Takes a sentence and return an object containing the location of each letter.middle(array)
: Returns the middle element of the array.
