Tests:
Object
const someOp = () => { console.info('boi') } const ops = { 0: someOp, 1: () => null, 2: () => null, 3: someOp, } for (let i = 0; i < 4; i++) { ops[i](); }
If statement
const someOp = () => { console.info('boi') } const enter = 0; const exit = 3; for (let i = 0; i < 4; i++) { if (i === enter) { someOp(); } else if (i === exit) { someOp(); } }

**Benchmark Explanation** The provided JSON represents two individual test cases for measuring the performance of JavaScript microbenchmarks on MeasureThat.net. **Test Case 1: Object Functions vs If Statements** In this test case, we have an object `ops` with four properties (0-3) that call either a function `someOp` or a no-op function. The `someOp` function simply logs "boi" to the console. The test iterates through each property in the `ops` object and calls its corresponding function. **Test Case 2: If Statement** In this test case, we have an if-else statement that checks if the current iteration index `i` is equal to a specific value (either `enter` or `exit`). If it is, the `someOp` function is called. The test iterates through each iteration of the loop and applies this condition. **Comparison of Approaches** In both test cases, we are comparing two approaches: 1. **Object Functions**: This approach uses an object with multiple functions to call in a loop. The benefits of this approach include: * Easy to extend or modify the number of functions being called. * Can be more memory-efficient than using if-else statements. However, it also has some drawbacks: * May have higher overhead due to function lookup and calling. 2. **If Statement**: This approach uses an if-else statement with a loop. The benefits of this approach include: * Can take advantage of compiler optimizations for simple conditional statements. * Often results in more efficient machine code generation. **Library: console** In both test cases, we use the `console` object to log messages to the console. The `console.info()` function is used in Test Case 1 and not explicitly mentioned in Test Case 2, but it's implied that the same logging functionality would be needed. **Special JS Feature/Syntax: None Mentioned** There are no special JavaScript features or syntaxes being tested in these benchmarks. **Other Alternatives** If you wanted to test these benchmarks on different platforms, browsers, or devices, MeasureThat.net allows you to add additional metadata to the benchmark definition, such as: * Browser version * Platform (e.g., Windows, macOS) * Device type (e.g., desktop, mobile) You can also modify the `Benchmark Definition` string to include custom logic or data structures to test specific scenarios. Keep in mind that the results may vary depending on the platform, browser, and device being used.
