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 @raubersn/lotide
Require it:
const _ = require('@raubersn/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(firstArray, secondArray): Will take in two arrays and console.log an appropriate message to the console. -
assertEqual(actual, expected): Function that takes in 2 values and returns true if they are equal and false otherwise. -
assertObjectsEqual(actual, expected): Will take in two objects and console.log an appropriate message to the console. -
countLetters(sentence): Function that takes in a sentence and returns a count of each of the letters in the sentence. -
countOnly(allItems, itemsToCount): The function takes in a collection of items and returns a specific subset of those items. -
eqArrays(firstArray, secondArray): The function takes in 2 arrays and returns true if the arrays are equal and false otherwise. The function is recursive and supports nested arrays. -
eqObjects(object1, object2): Returns true if both objects have identical keys with identical values. Otherwise you get back a big fat false! -
findKey(object, callback): The function takes in an object and callback and returns the first key that meets the criteria specified in callback. -
findKeyByValue(myObject, targetValue): The function takes in an object and a value and returns the first key that corresponds to that value. -
flatten(arr): The function takes in an array that contains elements including nested array of elements and returns a flattened version of the array. -
head(arr): The function takes in an array and returns the first element in the array. -
letterPositions(sentence): The function takes in a string and returns all indices of letter positions in the string. -
map(array, callBack): The function takes in an array and a callback and returns a new array based on the results of the callback on each item in the array. -
middle(arr): The function takes in an array and returns middle most element of the array. -
tail(arr): The function takes in an array and returns everything except the first element of the array. -
takeUntil(array, callBack): The function takes in an array and callback and returns a slice of the array based on the criteria specified in the callback. -
without(origin, values): Will return a subset of a given array, removing unwanted elements.
