Benchmark: aaaabbb - MeasureThat.net

Script Preparation code:

localStorage.setItem('foo', 'bar')
sessionStorage.setItem('foo', 'bar')

Tests:

1
var FOO = 'bar';
2
var FOO = localStorage.getItem('foo');
3
var FOO = sessionStorage.getItem('foo');
4
localStorage.setItem('foo2', 'bar2')
5
sessionStorage.setItem('foo2', 'bar2')

Measuring JavaScript performance is crucial for optimizing web applications. Let's break down the benchmark and its components.

**Benchmark Definition JSON**

The provided `benchmark definition` json represents a basic JavaScript microbenchmark. It consists of two parts:

1. **Script Preparation Code**: This section contains code that is executed before running the actual benchmark. In this case, it sets items in both local storage and session storage with the key 'foo' and value 'bar'.
2. **Html Preparation Code**: This section is empty, indicating that no additional HTML preparation is required for the benchmark.

**Individual Test Cases**

Each test case represents a small piece of JavaScript code that will be executed multiple times to measure its performance. The test cases are:

1. Assigning a string literal value to a variable `FOO`.
2. Retrieving an item from local storage using `localStorage.getItem('foo')`.
3. Retrieving an item from session storage using `sessionStorage.getItem('foo')`.
4. Setting an item in local storage with key 'foo2' and value 'bar2'.
5. Setting an item in session storage with key 'foo2' and value 'bar2'.

**Options Compared**

The main options being compared are:

* **Literal vs. Stored Value**: The first two test cases compare assigning a string literal value to a variable (`FOO`) versus retrieving it from local or session storage.
	+ Pros:
		- Literal values are typically faster and more efficient, as they don't require looking up values in storage.
		- Reduced memory usage, as stored values take up space in the browser's storage.
	+ Cons:
		- Requires manual string manipulation and concatenation (in the first test case).
* **Local vs. Session Storage**: The last three test cases compare setting an item in local storage versus session storage (`foo` vs. `foo2`).
	+ Pros:
		- Local storage has better security features, such as limiting storage capacity.
		- Provides a more persistent solution for storing data between sessions.
	+ Cons:
		- Less suitable for applications with limited storage capacity or high memory usage.
* **Variable Assignment vs. Retrieval**: The first three test cases compare assigning a value to a variable versus retrieving it from local or session storage.
	+ Pros:
		- Assigning values is typically faster and more efficient, as it doesn't require looking up values in storage.
		- Reduced memory usage, as stored values take up space in the browser's storage.
	+ Cons:
		- Requires manual string manipulation and concatenation (in test case 1).

**Library Usage**

In this benchmark, no libraries are explicitly mentioned or used.

**Special JS Features/Syntax**

No special JavaScript features or syntax are used in these test cases. They are basic, straightforward assignments and retrievals.

**Alternatives**

If you wanted to create a similar benchmark but with different options being compared, you could consider:

* Using global variables instead of local storage or session storage.
* Comparing the performance of different JavaScript engines (e.g., V8, SpiderMonkey).
* Examining the impact of caching mechanisms on performance.

Keep in mind that these alternatives would require modifying the benchmark definition json and test cases accordingly.
