Let's break down the provided benchmarking data and explain what's being tested, compared, and their pros and cons.
Benchmark Test
The test measures the performance of two different approaches to toggle an "active" class on an HTML input element based on its value. The test is comparing:
checkEmpty
that is defined within a separate scope, called when the user types in the input field.checkEmpty
defined globally (outside any other function or scope), also called when the user types in the input field.Pros and Cons of each approach:
clearTimeout
or document.removeEventListener
).Library usage
The test uses jQuery ($.trim
), which is a popular JavaScript library for DOM manipulation and event handling. The isEmpty
function is defined as a utility function within the benchmark definition, likely to avoid polluting the global namespace.
Special JS features or syntax
None of the provided code snippets use any advanced JavaScript features or syntax.
