Benchmark: nested function test

Tests:

not nested
a(1); function b(x) { return x + 1; } function a(x) { return b(x); }
nested
const o = a(1); o.b(); function a(x) { function b() { return x +1; } return { b } }

I'll explain what's being tested on the provided JSON.

**Benchmark Overview**

The benchmark measures the performance of two different approaches to returning an object with a nested property in JavaScript. The tests are designed to compare the execution speed of these approaches, specifically:

1. **Nested Function Call**: This approach creates a function `b` inside another function `a`, which returns the result of `b`. In this case, `b` takes an argument and returns its value plus 1.
2. **Object Creation**: This approach creates an object with a single property `b`, where the value of `b` is another function that takes an argument and returns its value plus 1.

**Options Compared**

The benchmark compares the execution speed of these two approaches:

* Approach 1: Nested Function Call
* Approach 2: Object Creation

**Pros and Cons**

* **Nested Function Call**:
	+ Pros:
		- Can be more intuitive for some developers who are familiar with function-calling patterns.
		- May have fewer overhead costs compared to creating an object with a nested property.
	+ Cons:
		- Can lead to slower execution times due to the overhead of function calls and lookups.
* **Object Creation**:
	+ Pros:
		- Typically faster than nested function calls, as it avoids the overhead of function calls and lookups.
		- May be more efficient for large-scale applications where objects are frequently created and updated.
	+ Cons:
		- Can be less intuitive for some developers who are not familiar with object creation patterns.

**Library Usage**

There is no library used in this benchmark. The code is self-contained and only uses built-in JavaScript features.

**Special JS Feature or Syntax**

None of the test cases use any special JavaScript features or syntax that would require additional explanation.

**Other Alternatives**

If you want to explore alternative approaches, consider:

* Using a decorator pattern to create a nested function without creating an object.
* Using a closure to create a nested function without using the `function` keyword.
* Optimizing the code using techniques like memoization or caching to reduce execution times.

Keep in mind that these alternatives might not be applicable to all use cases, and their performance may vary depending on the specific requirements of your application.
