Why is createElement More Efficient Than innerHTML for Adding Elements to the DOM?

Creating Elements Efficiently: Why createElement Outperforms innerHTML

While innerHTML tempting with its apparent simplicity, createElement offers several distinct advantages that enhance both performance and code maintenance.

Preserving DOM Element References and Event Handlers

When inserting new elements using innerHTML, existing references to DOM elements become void as the DOM is rebuilt. This becomes problematic when managing event handlers, as they are not automatically reattached to the new elements. Using createElement, references are maintained, and event handlers don't need to be manually reconfigured.

Optimizing for Bulk Additions

In scenarios involving multiple element additions, resetting innerHTML repeatedly can significantly degrade performance due to constant re-parsing and creation of elements. createElement streamlines this process by allowing the building of HTML in a string. While this may require more initial effort, it becomes more efficient with larger sets of additions.

Simplified Code and Improved Readability

In addition to its performance benefits, createElement promotes code simplicity and clarity. The make() function showcases how createElement can be conveniently employed to construct complex HTML elements with ease. This approach simplifies code, facilitating maintenance and readability.

By leveraging createElement, developers can optimize performance, preserve DOM references, and enhance code maintainability. While innerHTML remains a valid option for certain use cases, createElement emerges as the preferred choice for robust, efficient, and easily manageable web development.
