Function isShallowEqual

isShallowEqual(a: object, b: object): boolean
Performs a shallow equality comparison between two objects.

Two objects are considered shallowly equal if:
- They are the same reference.
- Or they have the same set of own enumerable keys and each corresponding value is strictly equal.
Nested objects are compared by reference, not by value.
Parameters
- a: object
- b: object
Returns boolean
Example
```
isShallowEqual({ x: 1 }, { x: 1 });
// → true
```
Example
```
isShallowEqual(
  { x: { y: 1 } },
  { x: { y: 1 } },
);
// → false
```
