Benchmark: React hook bind vs direct call

Script Preparation code:

function hook1(hookMsg) {
  function test(msg) {
    var d = hookMsg + msg;
  }
  return {
    test,
  }
}

function testRoot(hookMsg, msg) {
  var d = hookMsg + msg;
}

function hook2(hookMsg) {
  return {
    test: testRoot.bind(null, hookMsg)
  }
}

Tests:

hook1
hook1("Hook1").test("hello")
hook2
hook2("Hook2").test("hello")

I'll explain the benchmark in detail.

**Benchmark Overview**

The provided JSON represents a JavaScript microbenchmark on MeasureThat.net, which compares two approaches to binding functions in React hooks. The benchmark measures the performance difference between these approaches.

**Script Preparation Code**

The script preparation code is the same for both test cases:
```javascript
function hook1(hookMsg) {
  function test(msg) {
    var d = hookMsg + msg;
  }
  return { test };
}

function testRoot(hookMsg, msg) {
  var d = hookMsg + msg;
}

function hook2(hookMsg) {
  return { test: testRoot.bind(null, hookMsg) };
}
```
These functions define two React hooks, `hook1` and `hook2`. The `testRoot` function is used in both approaches.

**Html Preparation Code**

There is no HTML preparation code provided, which means that the benchmark only measures the performance of the JavaScript code itself.

**Test Cases**

The benchmark consists of two test cases:

1. `hook1`: This test case uses the `hook1` approach, where the `test` function is returned directly from the hook.
2. `hook2`: This test case uses the `hook2` approach, where the `test` function is bound to `null` using the `bind()` method before being returned by the hook.

**Options Compared**

The benchmark compares two options:

1. **Direct binding (hook1)**: The `test` function is returned directly from the hook.
2. **Bound binding (hook2)**: The `test` function is bound to `null` using the `bind()` method before being returned by the hook.

**Pros and Cons**

Here's a brief summary of the pros and cons of each approach:

**Direct Binding (hook1)**

Pros:

* Simpler and more efficient
* No unnecessary overhead from binding

Cons:

* May not work correctly in some environments where `this` is not bound to the correct context.

**Bound Binding (hook2)**

Pros:

* Works correctly in most environments, even when `this` is not bound to the correct context.
* Can be useful when working with callback functions or events.

Cons:

* Adds unnecessary overhead due to binding
* May be slower than direct binding for simple use cases.

**Other Considerations**

In modern JavaScript, both approaches are generally considered acceptable. However, if you're working in an environment where `this` context matters (e.g., older browsers), bound binding might be a better choice. On the other hand, if you're optimizing for performance and simplicity, direct binding might be the way to go.

**Library Usage**

There is no explicit library usage in this benchmark. However, React hooks rely on several internal libraries and frameworks that manage the state and lifecycle of components.

**Special JS Feature or Syntax**

This benchmark does not use any special JavaScript features or syntax beyond what's typically available in modern browsers. It's a straightforward comparison of two approaches to binding functions in React hooks.
