To check if an object is empty in JavaScript, do this: Object.keys(object).length === 0.

Here's how you do it:

const emptyObject = {};
const nonEmptyObject = { Hello: 'World!' };

// true
console.log(Object.keys(emptyObject).length === 0);

// false
console.log(Object.keys(nonEmptyObject).length === 0);
