Benchmark: Try catch fork - MeasureThat.net

Tests:

fn
const tryCatch = async (next, fn) => { try { await fn(); } catch (err) { next(err); } } const fnn = async () => { await console.log('hello'); } tryCatch(console.error, fnn); tryCatch(console.error, fnn); tryCatch(console.error, fnn); tryCatch(console.error, fnn);
fn error
const tryCatch = async (next, fn) => { try { await fn(); } catch (err) { next(err); } } const fnn = async () => { throw new Error("Error"); } tryCatch(console.error, fnn); tryCatch(console.error, fnn); tryCatch(console.error, fnn); tryCatch(console.error, fnn);
try
const fnn = async () => { await console.log('hello'); } (async () => { try { await fnn(); } catch (err) { console.error(err); } })(); (async () => { try { await fnn(); } catch (err) { console.error(err); } })(); (async () => { try { await fnn(); } catch (err) { console.error(err); } })(); (async () => { try { await fnn(); } catch (err) { console.error(err); } })();
catch
const fnn = async () => { throw new Error("Error");; } (async () => { try { await fnn(); } catch (err) { console.error(err); } })(); (async () => { try { await fnn(); } catch (err) { console.error(err); } })(); (async () => { try { await fnn(); } catch (err) { console.error(err); } })(); (async () => { try { await fnn(); } catch (err) { console.error(err); } })();

Let's dive into the world of JavaScript microbenchmarks on MeasureThat.net.

**Benchmark Definition**

The provided benchmark definition is a simple JavaScript function that demonstrates try-catch behavior with different execution scenarios. The script preparation code is empty, indicating that no additional setup or initialization is required for the benchmarks.

**Options Compared**

The benchmark compares four different options:

1. **try**: This option executes the `fnn` function inside a try block without any error handling.
2. **catch**: Similar to the try option, but with an empty catch block, which essentially does nothing when an error occurs.
3. **fn**: This option wraps the `fnn` function in a try-catch block and passes an error handler (`console.error`) to handle any errors that might occur during execution.
4. **try-fn-error**: This option is similar to the `fn` option, but with an additional `throw new Error("Error");` statement inside the function, simulating an error.

**Pros and Cons of Each Approach**

1. **try**: This approach has the lowest overhead since it doesn't require any error handling. However, if an error occurs, it will not be caught or handled in any way.
2. **catch**: Similar to the try option, but with an empty catch block. This approach also has low overhead but is essentially useless when an error occurs.
3. **fn**: This approach provides basic error handling by passing a console error handler. While it's better than the try and catch options, it may still not be sufficient in all cases.
4. **try-fn-error**: This approach simulates an error and tests how the browser handles it. It's useful for identifying issues related to error propagation.

**Library and Purpose**

There is no explicit library mentioned in the benchmark definition. However, `console.error` is used as a custom error handler, which suggests that MeasureThat.net provides a console-like interface for logging errors or other messages during testing.

**Special JS Features and Syntax**

The benchmark uses JavaScript's async/await syntax, which allows for writing asynchronous code that's easier to read and maintain. It also demonstrates the use of try-catch blocks with custom error handling using `console.error`.

**Other Alternatives**

If MeasureThat.net is not an option or if you're interested in exploring other alternatives:

* [Benchmark.js](https://benchmarkjs.com/): A popular benchmarking library for JavaScript.
* [Microbenchmark](https://github.com/vjeeman/microbenchmark): Another lightweight benchmarking library for Node.js and browser environments.
* [BenchmarkUa](https://benchmarkua.github.io/): A tool specifically designed for benchmarking UA strings and identifying differences between browsers.

Keep in mind that these alternatives might not provide the same level of customization or control as MeasureThat.net.
