JavaScript

Polyfill.io recently served malicious code, redirecting users to inappropriate sites. Subresource Integrity (SRI) can help prevent such issues by verifying script integrity.

I found this essay Primitive Obsession by Andrew Cairns interesting. The big example in it is this: Here the User function takes two string params, string being a primitive type, and here, quite easy to screw up by passing them in the wrong order and/or not pre-validating the values.

Sometimes it’s good to know when a browser feature is supported or not so you can do something. Perhaps load a polyfill or just choose a slightly different approach. This post looks at newish features in browsers and shows the test.

Michelle Barker’s technique for popover footnotes is great. Here we look at ways we could fight the content duplication. There are ups and downs.

This method enhances flexibility by allowing promises to be resolved or rejected remotely, simplifying and streamlining asynchronous code.

Server-side component rendering can improve data loading efficiency over client-rendered SPAs. Despite their benefits, such as out-of-order streaming, they have limitations, including slow server action updates and lack of support for client-side interactivity. React Query complements RSC by managing client-side data updates, addressing some of RSC’s drawbacks.

Let’s say you don’t know JavaScript. You’re a web designer and you’re focused largely on UI and UX. Let’s look at some things you could learn in a day that will give you that bang for the buck.

We can *mostly* use HTML alone for this API. But here, we’ll use CSS to style the “links” within paragraphs and a JS library to position them, in lieu of CSS anchoring.
