Tests:
Vanilla
function toggleActive() { this.parentElement.classList.toggle("active"); } window.addEventListener('DOMContentLoaded', function() { var FAQTrigger = document.querySelectorAll('.faq-list-content li h2'); FAQTrigger.forEach(function(trigger) { trigger.addEventListener('click', toggleActive, false) }) })
Jquery
$(document).on('click', '.faq-list-content li h2', function (event) { event.preventDefault(); this.parentElement.classList.toggle("active"); });

Let's break down the benchmark and explain what's being tested. **Benchmark Definition** The benchmark is comparing two approaches to toggle the active class on an element: vanilla JavaScript and jQuery. **Script Preparation Code** The script preparation code includes the jQuery library, which is loaded from a CDN. This suggests that the test case uses jQuery for its DOM manipulation capabilities. **Html Preparation Code** The HTML preparation code includes a sample webpage with multiple `<li>` elements containing `<h2>` headers and paragraphs of text. These elements will be used to trigger the toggleActive function. **Individual Test Cases** There are two test cases: 1. **Vanilla**: This test case uses vanilla JavaScript, which is executed directly in the browser. The script definition toggles the active class on an element when its parent node is clicked. 2. **Jquery**: This test case uses jQuery, a JavaScript library that provides additional DOM manipulation and event handling capabilities. The script definition uses jQuery's `$(document).on()` method to attach an event listener to the document, which toggles the active class on an element when the corresponding `<h2>` header is clicked. **Options Compared** The two options being compared are: 1. Vanilla JavaScript: This approach relies on native JavaScript functionality and does not require additional libraries or dependencies. 2. jQuery: This approach uses a third-party library to provide additional DOM manipulation and event handling capabilities. **Pros and Cons of Each Approach** **Vanilla JavaScript:** Pros: * Lightweight and efficient, as it only requires the browser's built-in functionality * Easy to implement and understand for developers familiar with native JavaScript Cons: * May require more manual effort for complex DOM manipulations * Does not provide additional features like event delegation or DOM traversal **jQuery:** Pros: * Provides a comprehensive set of utility functions for DOM manipulation, event handling, and other tasks * Easier to implement complex scenarios due to its abstraction layer * Wide adoption and community support Cons: * Adds an additional library dependency that may slow down page load times * May introduce additional overhead due to the jQuery library's implementation details **Library Used:** In this benchmark, jQuery is used for its DOM manipulation capabilities, specifically for attaching event listeners and toggling classes. **Special JS Feature or Syntax:** This benchmark does not explicitly use any special JavaScript features or syntax. However, it relies on modern JavaScript concepts like closures, arrow functions (in the script preparation code), and template literals (in the HTML preparation code). **Other Alternatives:** If you're interested in exploring alternative approaches to DOM manipulation and event handling, some options include: * React or Angular for building reusable UI components * Preact or Vue.js as alternatives to jQuery for small-scale applications * Vanillify libraries like LitElement or Embla Carousel for complex UI scenarios These alternatives can provide more features and flexibility, but may also introduce additional complexity and learning curves.
