Benchmark: strategy object vs switch statement

Tests:

strategy object
const strategyFunction = (option) => { const options = { option1: 'I am option 1', option2: 'I am option 2' } return options[option] } strategyFunction('option1'); strategyFunction('option2');
switch
const switchFunction = (option) => { switch(option) { case 'option1': return 'I am option 1' break; case 'option2': return 'I am option 1' break; } } switchFunction('option1'); switchFunction('option2');

Let's break down the provided benchmark and explain what's being tested, compared, and their pros/cons.

**What is being tested?**

The benchmark compares two approaches to handle different options:

1. **Strategy Object**: The first test case uses a strategy object (`const options = { ... }`) to map options to their corresponding values.
2. **Switch Statement**: The second test case uses a switch statement (`switch(option) { ... }`) to achieve the same result.

**What is compared?**

Both approaches are executed in the same way: for each option ('option1' and 'option2'), the function returns the corresponding value. However, their underlying logic differs:

* Strategy Object:
	+ Creates an object `options` with key-value pairs.
	+ Returns the value associated with the provided option using bracket notation (`options[option]`).
* Switch Statement:
	+ Uses a switch statement to check for each possible option and return the corresponding value.

**Pros and Cons of each approach:**

1. Strategy Object:
	+ Pros:
		- Easy to read and understand, especially for simple cases.
		- Encourages explicit and concise code.
	+ Cons:
		- May be less efficient due to the overhead of creating an object and using bracket notation.
2. Switch Statement:
	+ Pros:
		- Can be more efficient for large numbers of options, as it avoids object creation and uses a jump table.
	+ Cons:
		- Less readable and maintainable for complex cases or when options are added frequently.

**Library and syntax used:**

* No specific library is mentioned in the provided code snippets. However, the use of bracket notation (`options[option]`) suggests that JavaScript's object literal syntax is being utilized.
* The switch statement syntax is standard JavaScript, but it's worth noting that this syntax has been supported since ECMAScript 1999.

**Other alternatives:**

For larger-scale applications or performance-critical code, other approaches might be considered:

1. **Array-based approach**: Instead of using an object or a switch statement, you could use an array with option indices as keys and values.
2. **Function composition**: You could create a function that takes the option as input and returns the corresponding value, allowing for more flexibility in handling different options.
3. **Map data structure**: If the number of options is very large or dynamic, using a `Map` data structure might provide better performance.

Keep in mind that these alternatives may introduce additional complexity or trade-offs, so it's essential to weigh their pros and cons based on your specific use case and requirements.
