Let's break down what is being tested in this benchmark.
Benchmark Overview
The benchmark compares the performance of two approaches to add an element class:
jQuery addClass
: Using the jQuery library, which is a popular JavaScript library for DOM manipulation.javascript classList.add
: A native JavaScript method that allows you to add classes to elements without relying on libraries like jQuery.Options Compared
The benchmark tests two options:
A) jQuery addClass
with a manipulated jQuery instance (i.e., the jQuery library has been modified to behave differently than its standard behavior).
B) javascript classList.add
Pros and Cons of Each Approach
Library: jQuery
jQuery is a popular JavaScript library that simplifies DOM manipulation, event handling, and other tasks. In this benchmark, the jQuery addClass
option uses a manipulated instance of the library to compare its performance with the native javascript classList.add
method.
Special JS Feature/Syntax
There are no special JavaScript features or syntax mentioned in the benchmark definition or test cases. However, it's worth noting that the use of the classList
property and the add()
method is a modern JavaScript feature introduced in ECMAScript 2015 (ES6).
Other Alternatives
If you need to add classes to elements without using jQuery, other alternatives include:
setAttribute()
method with the class
attribute or the classList.add()
method.classList.add()
function as part of its API.className
prop.Keep in mind that each approach has its pros and cons, and the choice ultimately depends on your specific use case, performance requirements, and personal preference.
