This benchmark on MeasureThat.net compares two ways to create DOM elements in JavaScript:

Method 1: createElement

• Code: The test uses document.createElement('div') to create a new <div> element, then sets its inner HTML to "Hello" and returns the outerHTML of the div.
• Pros: This method is straightforward and widely used. It's clear and easy to understand.

Method 2: createContextualFragment

• Code: This method uses document.createRange().createContextualFragment(
  Hello
  ) to create a fragment containing the <div> element with "Hello" inside. It then gets the first child of the fragment and returns its outerHTML.
• Pros: This approach can be more efficient, especially when creating multiple DOM elements at once, as it avoids immediately adding them to the document tree.

Considerations:

• Performance: The benchmark results show that createElement is significantly faster in this specific case. However, performance can vary depending on factors like browser, complexity of the HTML, and the overall context of your code.
• DOM Manipulation: createContextualFragment offers more control over how elements are inserted into the DOM. It's often used in scenarios where you need to build complex structures or manipulate existing content without immediately affecting the visible page.

Alternatives:

• Virtual DOM Libraries: Libraries like React, Vue.js, and Angular use a virtual DOM representation to update the actual DOM efficiently. This can be significantly faster than directly manipulating the DOM for large applications.
• Template Literals (ES6): For simpler HTML creation, template literals (``) offer a concise and readable way to embed variables and expressions within strings.
