Benchmark: assign vs compareaa

Script Preparation code:

var obj = {a: 0, b: 4, c:43};

Tests:

assign
obj.a = 100;
compare A
if (obj.a !== 0) {}
compare B
if (obj.b !== 0) {obj.b = 1}
ass
obj.c = 12

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

**Benchmark Definition JSON**

The provided JSON defines a benchmark with the following characteristics:

* The benchmark is named "assign vs comparea" (although it seems there's a typo in the description field).
* There's no detailed description of what the benchmark measures, but based on the test cases, we can infer that it compares the performance of different operations: assignment (`obj.a = 100;`) and comparison (`if (obj.a !== 0) { ... }`).

**Script Preparation Code**

The script preparation code is a JavaScript snippet that creates an object `obj` with three properties: `a`, `b`, and `c`, initialized to 0, 4, and 43, respectively.

**Html Preparation Code**

There's no HTML preparation code provided, which means the benchmark doesn't require any specific HTML structure or content.

**Individual Test Cases**

The benchmark consists of four test cases:

1. **assign**: This test case measures the performance of a simple assignment operation: `obj.a = 100;`. The test case is executed by assigning a new value to the property `a` on the object `obj`.
2. **compare A**: This test case measures the performance of a comparison operation that checks if `obj.a` is not equal to 0 (`if (obj.a !== 0) { ... }`). The test case is executed by checking the condition without performing any action.
3. **compare B**: Similar to compare A, this test case measures the performance of another comparison operation that checks if `obj.b` is not equal to 0 (`if (obj.b !== 0) { obj.b = 1 }`). However, unlike compare A, it also performs an assignment inside the condition.
4. **ass**: This test case seems to have a typo in its name and should be "assign" instead.

**Library Usage**

None of the provided test cases use any external libraries. The benchmark relies solely on standard JavaScript functionality.

**Special JS Features or Syntax**

There are no special JavaScript features or syntax used in the test cases. They only rely on basic operations like assignment, comparison, and execution.

**Benchmark Results**

The latest benchmark results show the performance of each test case for Chrome 66 on a desktop Windows platform:

| Test Name | Executions Per Second |
| --- | --- |
| assign | 11947606.0 |
| compare A | 11782633.0 |
| compare B | 6056646.0 |

**Other Alternatives**

To create similar benchmarks, you could consider using other benchmarking frameworks or tools that support JavaScript, such as:

* jsbench
* Benchmark.js
* Perf

These tools provide more features and options for creating complex benchmarks, but the core concept remains the same: measuring performance by executing small code snippets multiple times.
