The State of ES5 on the Web

Build for the Web, Build on the Web, Build with the Web – Web Performance and Site Speed Consultant

If I was only able to give one bit of advice to any company: iterate quickly on a slow-moving platform.

Excellent advice from Harry (who first cast his pearls before the swine of LinkedIn but I talked him ‘round to posting this on his own site).

1. Opt into web platform features incrementally
2. Embrace progressive enhancement to build fast, reliable applications that adapt to your customers’ context
3. Write code that leans into the browser, not away from it

I’m not against front-end frameworks, and, believe me, I’m not naive enough to believe that the only thing a front-end framework provides is soft navigations, but if you’re going to use one, I shouldn’t be able to smell it.

Lived experience

I hold this truth to be self-evident: the larger the abstraction layer a web developer uses on top of web standards, the shorter the shelf life of their codebase becomes, and the more they will feel the churn.

If Not React, Then What? - Infrequently Noted

Put the kettle on; it’s another epic data-driven screed from Alex. The footnotes on this would be a regular post on any other blog (and yes, even the footnotes have footnotes).

This is a spot-on description of the difference between back-end development and front-end development:

Code that runs on the server can be fully costed. Performance and availability of server-side systems are under the control of the provisioning organisation, and latency can be actively managed by developers and DevOps engineers.

Code that runs on the client, by contrast, is running on The Devil’s Computer. Nothing about the experienced latency, client resources, or even available APIs are under the developer’s control.

Client-side web development is perhaps best conceived of as influence-oriented programming. Once code has left the datacenter, all a web developer can do is send thoughts and prayers.

As a result, an unreasonably effective strategy is to send less code. In practice, this means favouring HTML and CSS over JavaScript, as they degrade gracefully and feature higher compression ratios. Declarative forms generate more functional UI per byte sent. These improvements in resilience and reductions in costs are beneficial in compounding ways over a site’s lifetime.

I don’t have time to learn React - Keith Cirkel

React is a non-transferable skill.

React proponents might claim that React will teach you modern UI, but from what I’ve seen it barely copes with modern UI. autofocus is broken, custom elements don’t work in all but the experimental version, using any “modern” features like dialog or popovers requires useEffect, and the synthetic event system teaches you so little about how DOM actually works. This isn’t modern UI, it’s UI from 2013 at its inception. I don’t have the time left in my career to pick up UI paradigms that haven’t evolved much beyond from when Barack Obama was in office.

When I mentor early career developers and they ask me what they should learn, I can’t say React, they don’t have time. I mean sure, pick up enough React to land you the inevitable job doing it, but it’s not going to level up your career.

How Microsoft Edge Is Replacing React With Web Components - The New Stack

“And so what we did is we started looking at, internally, all of the places where we’re using web technology — so all of our internal web UIs — and realized that they were just really unacceptably slow.”

Why were they slow? The answer: React.

“We realized that our performance, especially on low-end machines, was really terrible — and that was because we had adopted this React framework, and we had used React in probably one of the worst ways possible.”
