Package Exports

v_is_empty_value
v_is_empty_value/dist/v_is_empty_value.cjs.js
v_is_empty_value/dist/v_is_empty_value.es.js

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.

🪁 How to use

    const { isEmpty, isNotEmpty, isEmptyNested, isNotEmptyNested } = require("v_is_empty_value")

or you can import...

    import v_is_empty_value from 'v_is_empty_value'
    const { isEmpty, isNotEmpty, isEmptyNested, isNotEmptyNested } = v_is_empty_value

List

    // Checks if a value is empty. Returns true if the value is empty, else false.
    isEmpty(v) 

    // Checks if a value is not empty. Returns true if the value is not empty, else false.
    isNotEmpty(v)

    // Checks if a nested value is empty. Returns true if the nested value is empty, else false.
    isEmptyNested(v)

    // Checks if a nested value is not empty. Returns true if the nested value is not empty, else false.
    isNotEmptyNested(v)

☑ Things it confirms Empty

// Empty
isEmpty()  //-> TRUE
isNotEmpty()  //-> FALSE

// Empty String
isEmpty("")  //-> TRUE
isNotEmpty("")  //-> FALSE

// Null
isEmpty(null)  //-> TRUE
isNotEmpty(null)  //-> FALSE

// Undefined
isEmpty(undefined)  //-> TRUE
isNotEmpty(undefined)  //-> FALSE

// NaN
isEmpty(NaN)  //-> TRUE
isNotEmpty(NaN)  //-> FALSE

// Object
isEmpty({})  //-> TRUE
isNotEmpty({})  //-> FALSE

// Array
isEmpty([])  //-> TRUE
isNotEmpty([])  //-> FALSE

☑ Few things it confirms NOT Empty

 isEmpty("demo_password_123456")  //-> FALSE
 isNotEmpty("demo_password_123456")  //-> TRUE

 isEmpty(new Date())  //-> FALSE
 isNotEmpty(new Date())  //-> TRUE

 isEmpty(new Error())  //-> FALSE
 isNotEmpty(new Error())  //-> TRUE

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