Benchmark: Switch vs If else CNC

Script Preparation code:

function returnName(name) {
            if (name === '1Y') {
                return 'oneYearRor';
            }
            if (name === '3Y') {
                return 'threeYearRor';
            }
            if (name === '5Y') {
                return 'fiveYearRor';
            }
            if (name === '10Y') {
                return 'tenYearRor';
            }
            if (name === 'SI') {
                return 'sinceInceptionRor';
            }
            if (name === 'YTD') {
                return null;
            }

};

function switchStatement(name) {
	switch(name) {
      case '1Y': return 'oneYearRor';
      case '3Y': return 'threeYearRor';
      case '5Y': return 'fiveYearRor';
      case '10Y': return 'tenYearRor';
      case 'SI': return 'sinceInceptionRor';
      default: return null;
	}
}

Tests:

If else statement
returnName('1Y') returnName('3Y') returnName('5Y') returnName('10Y') returnName('SI') returnName('YTD')
Switch statement
switchStatement('1Y') switchStatement('3Y') switchStatement('5Y') switchStatement('10Y') switchStatement('SI') switchStatement('YTD')

**What is tested?**

The provided JSON represents two JavaScript microbenchmarks: "If else statement" and "Switch statement". The benchmarks compare the performance of two common control structures in JavaScript: if-else statements and switch statements.

**Options compared**

In this benchmark, the following options are compared:

1. If-else statements
2. Switch statements

The benchmark tests how efficient each control structure is at determining the return value based on a set of predefined conditions.

**Pros and Cons**

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

* **If-else statements**
	+ Pros: Generally easier to read and maintain, more flexible for complex logic.
	+ Cons: Can be slower than switch statements due to the overhead of evaluating multiple conditions.
* **Switch statements**
	+ Pros: Typically faster than if-else statements since it only evaluates each case once.
	+ Cons: More verbose and harder to read, especially for large numbers of cases.

**Library/Function**

The provided benchmark uses a custom function `returnName` that takes a string argument and returns a specific value based on the input. This function is used to create both if-else and switch statement benchmarks.

**Special JS feature/syntax (None)**

There are no special JavaScript features or syntaxes being tested in this benchmark.

**Benchmark Preparation Code**

The provided JSON contains two functions: `returnName` for creating the if-else benchmark, and `switchStatement` for creating the switch statement benchmark. These functions take a string argument as input and return a specific value based on the input.

**Other alternatives**

In general, if you need to compare control structures, you can also consider using other alternatives like:

1. **Template literals**: Which allow you to write template strings that can be used with switch statements.
2. **Object-based comparison**: Using objects to represent different cases and comparing them using `===` or `==`.
3. **Regular expressions**: If the logic is more complex and involves patterns.

However, these alternatives may not provide a direct comparison between if-else and switch statements like the provided benchmark does.

In conclusion, this benchmark provides a simple yet effective way to compare the performance of two common control structures in JavaScript: if-else statements and switch statements.
