Benchmark: Simple value assignment

Tests:

One new value assigned
var x = 0 for (var i = 0; i < 10000; i++) { x = 1 x = 0 x = 0 x = 0 }
Multiple values assigned
var x = 0 for (var i = 0; i < 10000; i++) { x = 0 x = 1 x = 2 x = 3 }
No new value assigned
var x = 0 for (var i = 0; i < 10000; i++) { x = 0 x = 0 x = 0 x = 0 }

Let's dive into the world of JavaScript microbenchmarks.

The provided JSON represents a benchmark test case on MeasureThat.net, where users can create and run JavaScript microbenchmarks. The main goal is to compare the performance of different approaches for value assignment in a loop.

**What is being tested?**

In this benchmark, three individual test cases are compared:

1. **One new value assigned**: In this scenario, only one new value is assigned to `x` within the loop.
2. **Multiple values assigned**: Here, multiple new values are assigned to `x` within the loop.
3. **No new value assigned**: In this case, no new value is assigned to `x` at all.

**Options being compared**

The benchmark compares three approaches for assigning a value to `x`:

1. **Simple assignment**: Directly assign a value to `x`, e.g., `x = 0`.
2. **Assignment with intermediate values**: Assign an intermediate value to `x` before re-assigning it, e.g., `x = 0; x = 1; x = 0; x = 0`.
3. **No assignment**: Do not assign any new value to `x`.

**Pros and Cons**

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

* **Simple assignment (e.g., `x = 0`)**:
	+ Pros: Simple, straightforward, and easy to understand.
	+ Cons: May lead to issues with hoisting or variable scope if not managed carefully.
* **Assignment with intermediate values (e.g., `x = 0; x = 1; ...`)**:
	+ Pros: Can help avoid issues with hoisting or variable scope, but may be more complex and harder to understand.
	+ Cons: May introduce unnecessary operations or computations, especially if the intermediate values are not simple literals.
* **No assignment**: In this case, there is no value assigned to `x`, so no computation occurs.

**Library usage**

There is no explicit library mentioned in the provided code snippets. However, JavaScript engines like Firefox typically use their own internal optimizations and algorithms for executing scripts, which may include various libraries or frameworks.

**Special JS features or syntax**

The benchmark does not explicitly test any special JavaScript features or syntax, such as async/await, closures, or modules. It focuses on a straightforward assignment scenario.

In summary, the MeasureThat.net benchmark tests three approaches for value assignment in a loop: simple assignment, assignment with intermediate values, and no assignment. The choice of approach can impact performance, readability, and maintainability.
