Let's break down the provided benchmark and explain what's being tested.
What is being tested?
The test compares two approaches to pass data to a function:
"object parameter"
): In this approach, a single object is created and passed as an argument to the function."argument parameter"
): In this approach, multiple individual values are passed as separate arguments to the function.The test measures which approach is faster, i.e., which one requires less time to execute.
Options compared
Two options are being compared:
Pros and Cons of each approach
Here's a brief analysis of each approach:
Other considerations
When choosing between these approaches, consider the specific requirements of your use case:
Library used
None, as there is no explicit library mentioned in the benchmark.
Special JS feature or syntax
There isn't any special JavaScript feature or syntax being tested. The test focuses on comparing two fundamental approaches to passing data to a function.
Benchmark result interpretation
The latest benchmark results show that passing individual arguments ("argument parameter"
)) is faster than passing an object ("object parameter"
)) in this specific test case, with Safari 10 achieving approximately 85,233,344 executions per second compared to Safari 10 achieving approximately 49,733,688 executions per second. However, keep in mind that these results may not be representative of other browsers or use cases.
