Benchmark: if else VS switch true

Tests:

switch true
var hostname = "google.com"; switch (true) { case hostname === "localhost": return "localhost"; case hostname.startsWith("sandpit-"): return "https://auth-sandpit.com"; case hostname.includes("dev.com"): return `https://qa-devau.auth0.com`; default: return "https://auth.com"; }
if-else
var hostname = "google.com"; if( hostname === "localhost") { return "localhost"; } else if(hostname.startsWith("sandpit-")) { return "https://auth-sandpit.com"; } else if(hostname.includes("dev.com")) { return `https://qa-devau.auth0.com`; } else { return "https://auth.com"; }

Let's dive into the benchmark and explore what's being tested.

**Benchmark Definition**

The benchmark definition is a JSON object that describes the test case. In this case, there are two test cases: "if else VS switch true" and its variants. The main difference between these test cases is the control flow mechanism used to make decisions.

**Options Compared**

Two options are being compared:

1. **Switch Statement**: The first option uses a `switch` statement with a boolean value (`true`) as the condition. This means that the code will execute different blocks of code based on the value of the boolean expression.
2. **If-Else Chain**: The second option uses an if-else chain to make decisions. In this case, multiple `if` statements are chained together to check different conditions.

**Pros and Cons**

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

**Switch Statement**

Pros:

* Can be more efficient than if-else chains for certain use cases (e.g., when dealing with discrete values).
* Can lead to better code organization and readability.

Cons:

* May not be suitable for all scenarios, especially those that require complex decision-making.
* Boolean switch statements like this one can be less readable due to the lack of clear conditionals.

**If-Else Chain**

Pros:

* More flexible than switch statements and can handle more complex conditions.
* Easy to read and understand, especially for simple use cases.

Cons:

* Can lead to longer execution times and increased complexity in large codebases.
* May result in duplicated code if not implemented carefully (e.g., using early returns).

**Library: `includes()`**

The benchmark uses the `includes()` method from JavaScript's standard library. This method is used to check if a string contains another string.

In this specific case, the `includes()` method is used to check if the `hostname` variable starts with "sandpit-".

The `includes()` method is generally efficient but can lead to slower performance for large strings due to its implementation details.

**Special JS Feature or Syntax**

There is no special JavaScript feature or syntax being tested in this benchmark. It's a straightforward comparison of two control flow mechanisms.

**Other Alternatives**

If you were to rewrite this benchmark with alternative approaches, some options could be:

* Using `switch` statements with string literals instead of boolean values.
* Implementing the if-else chain using loops (e.g., using `while` loops).
* Using different decision-making mechanisms like regular expressions or function calls.

Keep in mind that these alternatives might change the performance characteristics and complexity of the benchmark.
