What Google AMP means for the JavaScript community

Google AMP (Accelerated Mobile Pages) is an open-source project aimed at improving mobile web performance. It achieves this by providing a streamlined version of HTML and CSS, along with a JavaScript library that helps manage resource loading and rendering.

How does it work?

When a user visits an AMP page, the content is preloaded from Google's cache, which reduces the load time significantly. The AMP framework also enforces best practices for optimizing image sizes, lazy-loading resources, and reducing the amount of custom JavaScript.

Implications for the JavaScript community

The introduction of AMP has several implications for the JavaScript community:

1. Limited use of custom JavaScript

The AMP framework requires that custom JavaScript be kept to a minimum. This means that developers must think carefully about the functionality they want to add to their pages and consider whether it's necessary to use custom JavaScript or if there's a built-in solution available.

2. Emphasis on performance

Performance is a vital aspect of mobile browsing, and AMP emphasizes this in many ways. From enforcing image optimization to lazy-loading resources, the framework encourages developers to deliver fast-loading pages that enhance the user experience.

3. Adoption of emerging web technologies

AMP encourages the use of emerging web technologies such as Web Components, Service Workers, and Web Animations. This means that developers who embrace AMP may find themselves learning new skills that will be valuable in the future.

Getting started with AMP

To get started with AMP, you'll need to include the AMP script in your HTML head:

You can then create your AMP page using the AMP HTML specification. Here's an example of an AMP page with an image and a video:

Conclusion

Google AMP is a valuable tool for improving mobile web performance and delivering fast-loading pages. While it does require developers to limit their use of custom JavaScript and consider performance carefully, its emphasis on emerging web technologies means that it has the potential to drive innovation and learning in the JavaScript community.
