Benchmark: Direct call vs bind vs call vs apply (don't re-create bound function every time)

Script Preparation code:

function test(msg) {
  var d = msg;
}

var boundTest = test.bind(null)

Tests:

direct call
test("Hello");
bind
boundTest("Hello");
call
test.call(null, "Hello");
apply
test.apply(null, ["Hello"]);

Let's dive into the world of JavaScript microbenchmarks.

**Benchmark Definition JSON**

The provided JSON represents a benchmark test case on MeasureThat.net. The test compares the performance of four different approaches to invoke a function: `direct call`, `bind`, `call`, and `apply`. These approaches are used to create a bound version of the same function, which is created by binding the `null` value as the first argument.

**Options Compared**

The options compared in this benchmark test case are:

1. **Direct Call**: Invoking the function directly using its name.
2. **Bind**: Using the `bind()` method to create a bound version of the function.
3. **Call**: Invoking the bound function using its `call()` method.
4. **Apply**: Invoking the bound function using its `apply()` method.

**Pros and Cons**

Each approach has its own pros and cons:

1. **Direct Call**:
	* Pros: Simple, efficient, and widely supported.
	* Cons: May incur overhead due to the need for argument resolution and caching.
2. **Bind**:
	* Pros: Can be used to create a bound version of a function that takes an arbitrary number of arguments.
	* Cons: Creates a new function object each time it's called, which can lead to increased memory usage.
3. **Call**:
	* Pros: Efficient and widely supported.
	* Cons: Requires the target object to be available, and may incur overhead due to argument resolution.
4. **Apply**:
	* Pros: Can be used to invoke a bound function with a fixed set of arguments.
	* Cons: May incur overhead due to argument resolution and caching.

**Library Used**

There is no library explicitly mentioned in the provided JSON. However, it's likely that the `bind()`, `call()`, and `apply()` methods are part of the JavaScript Standard Library or a browser-specific implementation.

**Special JS Feature or Syntax**

The benchmark test case uses special syntax related to function invocation:

* **`bind()`**: Creates a new bound version of a function.
* **`call()`**: Invokes a bound function with a fixed set of arguments.
* **`apply()`**: Invokes a bound function with an array of arguments.

**Other Alternatives**

There are alternative approaches to invoke functions, such as:

1. **Arrow Functions**: A concise syntax for defining small, anonymous functions.
2. **Async/Await**: A syntax for writing asynchronous code that's easier to read and maintain.
3. **Closures**: A way to create private variables and functions within a scope.

However, these alternatives are not relevant to the specific benchmark test case provided.

I hope this explanation helps you understand the JavaScript microbenchmark test case!
