just-is-empty function fails to detect symbol properties in objects

[palashmon]

Package name:

• just-is-empty

URL:

• https://anguscroll.com/just/just-is-empty

Issue Description:

• The isEmpty() function, as currently implemented, fails to correctly detect when an object has properties with symbols as keys. This can result in incorrect output when using the function to check if an object is empty.

Steps to reproduce:

1. Create an object with a symbol property:

   const isEmpty = require('just-is-empty');
   
   const mySymbol = Symbol('mySymbol');
   const myObject = {
     [mySymbol]: 7
   };

2. Call the isEmpty() function with myObject as the argument:

   console.log(myObject);	// {[Symbol("mySymbol")]: 7}
   isEmpty(myObject);		// true

Expected output: false
Actual output: true
