Checks if the passed value is an object or not.
|
|
|
|
- Uses the `Object` constructor to create an object wrapper for the given value.
|
|
- If the value is `null` or `undefined`, create and return an empty object.
|
|
- Otherwise, return an object of a type that corresponds to the given value.
|
|
|
|
```js
|
|
const isObject = obj => obj === Object(obj);
|
|
```
|
|
|
|
```js
|
|
isObject([1, 2, 3, 4]); // true
|
|
isObject([]); // true
|
|
isObject(['Hello!']); // true
|
|
isObject({ a: 1 }); // true
|
|
isObject({}); // true
|
|
isObject(true); // false
|
|
```
