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 @sandeepgill62/lotide
Require it:
const _ = require('@sandeepgill62/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertEqual(actual, expected)
: This function helps to test code. -
head(array)
: This function returns the first item in the array -
tail(array)
: This function returns the "tail" of an array: everything except for the first item (head) of the provided array. -
eqArrays(array1, array2)
: This function which takes in two arrays and returns true or false, based on a perfect match. -
assertArraysEqual(array1, array2, expected)
: This function which will take in two arrays and console.log an appropriate message to the console. -
without(source, itemsToRemove)
: This function which will return a subset of a given array, removing unwanted elements. -
flatten(array)
: This function which will take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array. -
middle(array)
: This function which will take in an array and return the middle-most element(s) of the given array. -
countOnly(allItems, itemsToCount)
: This function should take in a collection of items and return counts for a specific subset of those items -
countLetters(letters)
: This function should take in a sentence (as a string) and then return a count of each of the letters in that sentence. -
letterPositions(sentence)
: This function which will return all the indices (zero-based positions) in the string where each character is found -
findKeyByValue(object, value)
: This function which takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined. -
eqObjects(object1, object2)
: This function which will take in two objects and returns true or false, based on a perfect match. -
assertObjectsEqual(actual, expected)
: This function which will take in two objects and console.log an appropriate message to the console. -
map(array, callback)
: This function which will take in array and callback function. This function will provide the result with array according to callback function definition. -
findKey(object, callback)
: This function which will take in obejct and callback function. This function will provide the result with object according to callback function definition. -
takeUntil(array, callback)
: This function which will take in array and callback function. Each array element will check callback function if condition meets according to values.
