Autogenerated LLM Summary (model gpt-4o-mini, generated one month ago):

This benchmark compares the performance of two different methods for retrieving numerical values based on string keys in JavaScript: using a Map data structure versus using a switch statement. Here's a breakdown of what is tested, the pros and cons of each approach, and alternative options.

Benchmark Options

Using Map:
- Test Code: Consists of numerous calls to numberMap.get() with string keys (like numberMap.get('one'), numberMap.get('two'), etc.).
- Execution Speed: This method shows a high execution speed of approximately 80,384,040 executions per second.
Using Switch:
- Test Code: Consists of function calls to getNumberValue() which uses a switch statement for return values based on string input.
- Execution Speed: This implementation shows a lower execution speed of about 445,163.69 executions per second.

Pros and Cons

Pros of Using `Map`:

Performance: The Map approach is significantly faster due to its underlying data structure, which allows for quicker key-value retrieval.
Simplicity: It can be defined in a simpler way, as adding or removing key-value pairs from a Map is straightforward.
Dynamic Keys: Maps can easily handle dynamic keys and maintain the order of insertion, which can be useful in various scenarios.

Cons of Using `Map`:

Memory Overhead: A Map might use more memory than a simple function with a switch statement, especially for a large number of entries.
Complexity for Small Datasets: For a small number of fixed values, the use of a Map might be overkill.

Pros of Using `Switch`:

Clarity: The switch structure is clear for small, fixed datasets where specific conditions are checked.
Memory Efficiency: This method may consume less memory as it does not require allocating space for a map.

Cons of Using `Switch`:

Performance Bottleneck: The performance slows down significantly as the number of cases increases; each case in a switch must be compared.
Less Flexible: Adding or removing values from a switch requires modifying code directly, leading to more maintenance.

Other Considerations

Alternatives:
- Object Lookup: Another common approach in JavaScript for key-value storage is using a plain JavaScript object instead of a Map. However, objects do not maintain the order of keys, which may be a consideration based on the requirement.
- Array Lookup: If keys are contiguous integers, an array might be the most performant option, allowing for direct indexing.
- Functions or Lookup Tables: If values are computed based on more complex logic, functions defined as lookup tables may provide a middle ground for clarity and performance.

In conclusion, while both methods can achieve the same functionality, the benchmark clearly demonstrates that using a Map for key-value retrieval is vastly superior in terms of performance, especially for larger datasets. The switch statement, while easy to read and maintain for small, static data mappings, becomes inefficient as the number of cases grows, making the Map a generally better choice in scalable applications.

This benchmark compares the performance of two different methods for retrieving numerical values based on string keys in JavaScript: using a `Map` data structure versus using a `switch` statement. Here's a breakdown of what is tested, the pros and cons of each approach, and alternative options.

### Benchmark Options

1. **Using `Map`:**
   - **Test Code:** Consists of numerous calls to `numberMap.get()` with string keys (like `numberMap.get('one')`, `numberMap.get('two')`, etc.).
   - **Execution Speed:** This method shows a high execution speed of approximately **80,384,040 executions per second**.

2. **Using `Switch`:**
   - **Test Code:** Consists of function calls to `getNumberValue()` which uses a `switch` statement for return values based on string input.
   - **Execution Speed:** This implementation shows a lower execution speed of about **445,163.69 executions per second**.

### Pros and Cons

#### Pros of Using `Map`:
