Overview of the Benchmark
The provided JSON data represents a JavaScript microbenchmark, specifically designed to measure the performance difference between two approaches: executing code inside and outside a function.
Benchmark Definition
The benchmark is defined by two script preparation codes:
testasd
:isEmpty
that checks if an input element has no value.There are two main test cases:
checkEmpty
that removes the "active" class from an element if it's empty, and adds it otherwise.keyup
event of each input field using jQuery.Comparison
The main difference between these two approaches is where the logic is executed:
checkEmpty
function is defined separately and then attached to the event handler. This approach has the following pros:However, both approaches have their use cases:
Other Considerations
.trim()
, .removeClass()
, and .addClass()
. jQuery can also improve performance by providing optimized DOM manipulation and event handling.RawUAString
