Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (v_is_empty_value) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

👨‍💻 v_is_empty_value

Simple checker for Empty/NotEmpty values. Checking Numbers, Null, NaN, Strings, Objects, Arrays...Will also detect instance of Date() object and return "not-empty" value for it.

🔩 Install using command

npm install v_is_empty_value

🎭 And save for later re-install

npm install v_is_empty_value --save

🪁 How to use

const { isEmpty, notEmpty, isEmptySync, notEmptySync } = require("v_is_empty_value");

or you can import...

import v_is_empty_value from 'v_is_empty_value';
const { isEmpty, notEmpty, isEmptySync, notEmptySync } = v_is_empty_value;

☑ Things it confirms Empty

// Empty
await isEmpty()  //-> TRUE
isEmptySync()  //-> TRUE

await notEmpty()  //-> FALSE
notEmptySync()  //-> FALSE

// Empty String
await isEmpty("")  //-> TRUE
isEmptySync("")  //-> TRUE

await notEmpty("")  //-> FALSE
notEmptySync("")  //-> FALSE

// Null
await isEmpty(null)  //-> TRUE
isEmptySync(null)  //-> TRUE

await notEmpty(null)  //-> FALSE
notEmptySync(null)  //-> FALSE

// Undefined
await isEmpty(undefined)  //-> TRUE
isEmptySync(undefined)  //-> TRUE

await notEmpty(undefined)  //-> FALSE
notEmptySync(undefined)  //-> FALSE

// NaN
await isEmpty(NaN)  //-> TRUE
isEmptySync(NaN)  //-> TRUE

await notEmpty(NaN)  //-> FALSE
notEmptySync(NaN)  //-> FALSE

// Object
await isEmpty({})  //-> TRUE
isEmptySync({})  //-> TRUE

await notEmpty({})  //-> FALSE
notEmptySync({})  //-> FALSE

// Array
await isEmpty([])  //-> TRUE
isEmptySync([])  //-> TRUE

await notEmpty([])  //-> FALSE
notEmptySync([])  //-> FALSE

☑ Few things it confirms NOT Empty

await isEmpty("demo_password_123456")  //-> FALSE
await notEmpty("demo_password_123456")  //-> TRUE

await isEmpty(new Date())  //-> FALSE
await notEmpty(new Date())  //-> TRUE

await isEmpty(new Error())  //-> FALSE
await notEmpty(new Error())  //-> TRUE

await isEmpty(new Promise((resolve, reject) => resolve(true)))  //-> FALSE
await notEmpty(new Promise((resolve, reject) => resolve(true)))  //-> TRUE

🚀 Benchmarking

Performance depends on whether you're using asynchronous or synchronous version. Sync versions tend to run slower. Currently asynchronous version achieves up to 20k checks per millisecond, while sync version does up to 8k checks per ms.

NOTE: This version improves only performance of the code and cuts down on execution time, thus resulting in such performance uplift without changing/breaking any test cases.
