A lightweight utility library for JavaScript that provides functions to determine if a value is empty, covering strings, objects, and arrays.
You can install isempty-util via npm:
npm install isempty-utilconst { isEmpty } = require('isempty-util');
// Check if a value is empty
console.log(isEmpty('')); // true
console.log(isEmpty({})); // true
console.log(isEmpty([])); // true
isEmpty(value)
Determines if a provided value is considered empty.
- value: The value to be evaluated.
- Returns true if the value is empty; otherwise, returns false.
const { isEmpty } = require('isempty-util');
// Test cases for isEmpty function
console.log(isEmpty('')); // Expected: true (empty string)
console.log(isEmpty({})); // Expected: true (empty object)
console.log(isEmpty([])); // Expected: true (empty array)
console.log(isEmpty('Hello')); // Expected: false (non-empty string)
console.log(isEmpty({ key: 'value' })); // Expected: false (non-empty object)
console.log(isEmpty([1, 2, 3])); // Expected: false (non-empty array)
console.log(isEmpty(null)); // Expected: true (null)
console.log(isEmpty(undefined)); // Expected: true (undefined)
console.log(isEmpty(0)); // Expected: false (number)
console.log(isEmpty(false)); // Expected: false (boolean)
value (*): The value to check. Returns true if the value is empty, otherwise false.
