Benchmark Definition
The benchmark definition is represented by two different approaches:
2 * 3
- This approach tests the performance of simple arithmetic operations, specifically multiplication, without using any functions or libraries.eval("2 * 3")
- This approach tests the performance of the built-in JavaScript function eval()
, which executes a string as JavaScript code.Pros and Cons
Library Usage
The test case uses the built-in eval()
function, which is a part of the JavaScript language. Its purpose is to execute a string as JavaScript code.
Special JS Features/Syntax
There are no special JavaScript features or syntax mentioned in this benchmark. However, it's worth noting that some benchmarks may use advanced features like async/await, Promises, or modern ES6+ syntax to test performance under different scenarios.
Other Alternatives
If you wanted to create a similar benchmark, you could consider adding more options, such as:
func(2, 3)
.for (i = 0; i < 10000; i++) { /* code */ }
.{ a: 1, b: 2 }
.These alternatives would provide a more comprehensive view of JavaScript performance under different scenarios.
Keep in mind that when creating or modifying benchmarks, it's essential to consider factors like:
