Benchmark: Passing Objects vs individual arguments

Tests:

object parameter
var sprite = {a:1, b:2}; function t(a) { return a.a + a.b; } t(sprite);
argument paramater
var sprite = {a:1, b:2}; function t(a, b) { return a + b; } t(sprite.a, sprite.b);

Let's break down the provided benchmark and explain what's being tested.

**What is being tested?**

The test compares two approaches to pass data to a function:

1. Passing an object (`"object parameter"`): In this approach, a single object is created and passed as an argument to the function.
2. Passing individual arguments (`"argument parameter"`): In this approach, multiple individual values are passed as separate arguments to the function.

The test measures which approach is faster, i.e., which one requires less time to execute.

**Options compared**

Two options are being compared:

1. **Passing an object**: This approach involves creating a single object and passing it as an argument to the function.
2. **Passing individual arguments**: This approach involves passing multiple individual values as separate arguments to the function.

**Pros and Cons of each approach**

Here's a brief analysis of each approach:

* **Passing an object**:
	+ Pros: Can be more convenient, especially when working with complex data structures or large amounts of data.
	+ Cons: May incur additional overhead due to object creation and manipulation, potentially slowing down the function execution.
* **Passing individual arguments**:
	+ Pros: Typically faster, as it avoids the overhead associated with object creation and manipulation.
	+ Cons: Requires more code to define multiple separate argument names, which can be cumbersome.

**Other considerations**

When choosing between these approaches, consider the specific requirements of your use case:

* If you're working with complex data structures or large amounts of data, passing an object might be a better choice.
* If you need faster execution and are comfortable with more code, passing individual arguments might be a better option.

**Library used**

None, as there is no explicit library mentioned in the benchmark.

**Special JS feature or syntax**

There isn't any special JavaScript feature or syntax being tested. The test focuses on comparing two fundamental approaches to passing data to a function.

**Benchmark result interpretation**

The latest benchmark results show that passing individual arguments (`"argument parameter"`)) is faster than passing an object (`"object parameter"`)) in this specific test case, with Safari 10 achieving approximately 85,233,344 executions per second compared to Safari 10 achieving approximately 49,733,688 executions per second. However, keep in mind that these results may not be representative of other browsers or use cases.

**Alternatives**

If you're interested in exploring alternative approaches or libraries for benchmarking JavaScript performance, consider the following:

* **Benchmarking libraries**: Libraries like Benchmark.js or jsperf can help you write and run benchmarks more efficiently.
* **Benchmarking frameworks**: Frameworks like Benchmark Suite or JSMeter provide a structured approach to benchmarking JavaScript performance.

I hope this explanation helps software engineers understand what's being tested in the provided benchmark!
