Add **`Object.isEmpty(value)`** to return **`true`** only when **`value`** has zero own string or symbol keys (otherwise **`false`** , primitives throw). The repository contains the reference implementation, polyfill helper, documentation, and tests to explore adding this built-in to JavaScript.

**Motivation and examples**

- Avoid verbose patterns (**`Object.keys(obj).length === 0`**, etc.) that miss symbol keys or objects without prototypes.

- Provide a clear primitive that engines can optimize, aligning with other **`Object.*`** utilities. \*

```javascript
js

```

```javascript
Object.isEmpty({}); // true
Object.isEmpty({ a: 1 }); // false
Object.isEmpty(Object.create(null)); // true
Object.isEmpty(Symbol("x")); // TypeError

```

**Open questions for feedback**

1. Should primitives be coerced with **`ToObject`** (like **`Object.keys`** ) or should the method throw to surface bugs?

2. Is the name **`Object.isEmpty`** ideal, or should we consider alternatives such as **`Object.isEmptyObject`**?

3. What optimizations or exotic-object behaviors (e.g., proxies, host objects) should be specified explicitly?

There is [a brand new proposal](https://github.com/tc39/proposal-object-keys-length) for giving the _number_ of keys, which would cover this. You may be interested in following along there.
