Benchmark: comparison of object vs number

Tests:

Object
const obj1 = { type: 1 }; const obj1b = obj1; const obj2 = { type: 2 }; for( let i = 0; i < 10000; i++ ) { const res = obj1 === obj1b; } for( let i = 0; i < 10000; i++ ) { const res = obj1 === obj2; }
Number
const obj1 = 1 const obj1b = 1; const obj2 = 2; for( let i = 0; i < 10000; i++ ) { const res = obj1 === obj1b; } for( let i = 0; i < 10000; i++ ) { const res = obj1 === obj2; }

Let's break down the provided benchmark JSON and test cases.

**Benchmark Definition JSON**

The benchmark definition represents the framework for comparing different approaches. It doesn't explicitly define what is being tested, but based on the test cases, it appears to be testing two approaches:

1. Comparing objects (using `===` operator)
2. Comparing numbers (using `===` operator)

**Options Compared**

There are two options compared in this benchmark:

1. **Object Comparison**: Using `obj1 === obj1b` and `obj1 === obj2` to compare the object `obj1` with itself (`obj1b`) and another object (`obj2`). This is likely being used to test the performance of object reference comparison.
2. **Number Comparison**: Using `obj1 === obj1b` and `obj1 === obj2` to compare the number `obj1` with another number (`obj1b`) and an object (likely using a primitive value 2). This is likely being used to test the performance of numerical comparison.

**Pros and Cons**

* **Object Comparison**: The use of `===` operator for object reference comparison can lead to slower performance due to the complexity of object references. Additionally, this approach may not accurately reflect real-world scenarios where objects are compared using other methods (e.g., equality checks).
* **Number Comparison**: Using numerical values for comparison is likely faster than comparing objects, as numbers can be compared directly without the overhead of object reference resolution.

**Other Considerations**

There is no special JavaScript feature or syntax being tested in this benchmark. The focus is on comparing basic data types (objects and numbers) using a specific operator (`===`).

**Library Usage**

There is no explicit library usage mentioned in the provided code snippets, but it's possible that some libraries (e.g., Lodash or other utility libraries) might be used implicitly or by default.

**Special JS Features/Syntax**

None are explicitly mentioned in this benchmark.
