Benchmark: throw vs no-throw function

HTML Preparation code:

<div id="test"></div>

Tests:

throw
const o = JSON.parse('{"name":"John", "age":31, "city":"New York"}'); if (o.name === undefined) throw new Error('Bla');
No throw
const o = JSON.parse('{"name":"John", "age":31, "city":"New York"}');

I'd be happy to explain the benchmark test and its various components.

**What is being tested?**

The provided JSON represents a JavaScript microbenchmark on MeasureThat.net, which compares two approaches: throwing an error versus not throwing an error in a specific scenario.

**Options compared:**

There are only two options being compared:

1. **Throwing an error**: The code throws an Error instance with the message "Bla" using the `throw` keyword.
2. **No throw**: The code does not throw an error, instead allowing the JavaScript interpreter to handle any potential errors that might occur.

**Pros and Cons:**

* **Throwing an error (throw):**
	+ Pros:
		- It forces the interpreter to handle any potential errors, which can help in debugging and error handling.
		- It's a common way to signal that something has gone wrong in a program.
	+ Cons:
		- It can slow down the execution of code due to the overhead of throwing an exception.
		- In some cases, it may not be necessary or desirable to throw an error if it doesn't provide any useful information.
* **No throw:**
	+ Pros:
		- It avoids the overhead of throwing an exception, which can improve performance in certain scenarios.
		- It allows the interpreter to handle any potential errors that might occur without explicitly throwing one.
	+ Cons:
		- It may not provide enough information about what went wrong if an error occurs.

**Library and purpose:**

The `JSON.parse()` function is used in both test cases. This method parses a JSON string into a JavaScript object, allowing us to easily access the data within it. In this case, we're using it to parse a sample JSON string that contains personal data.

**Special JS feature or syntax:**

There are no special JavaScript features or syntaxes being tested in this benchmark. It's purely focused on comparing two different approaches to handling potential errors.

**Other alternatives:**

If you were looking for alternative ways to handle errors or exceptions, some common approaches include:

* **Try-catch blocks**: This involves wrapping code that might throw an exception within a `try` block and catching the exception with a corresponding `catch` block.
* **Error objects**: Instead of throwing an error instance, you could create a custom error object using a class constructor or the built-in `new Error()` method.
* **Asynchronous programming models**: Depending on your specific use case, you might consider using asynchronous programming models like Promises or async/await to handle errors and exceptions in a more elegant way.

In summary, this benchmark is designed to compare two approaches to handling potential errors: throwing an exception versus not throwing one. The results can help users understand the performance implications of each approach and make informed decisions about how to handle errors in their own code.
