Internet Weekly #135 | Stefan Judis Internet Improvement

Guten Tag! Guten Tag! 👋

What is the ECMAScript 2.7 proposal stage? Are if statements coming to CSS? And the way most of the new Safari 18 beta launch’s options are secure to make use of in the present day?

Activate the Internet Weekly tune and discover all of the solutions beneath. Take pleasure in!

Paweł listens to “Slum Village – Issue” and says:

Slum Village! Feels like early days SV, however this one is just not produced by Dilla. So so so good!

Do you need to share your favourite tune with the Internet Weekly group? Hit reply; there are three extra songs left within the queue.

Let’s kick issues off with a fast ECMAScript TIL!

You may know that new JavaScript options are outlined and proposed through ECMAScript proposals. A brand new characteristic has to cross a number of proposal levels earlier than it is added to JavaScript. The levels go from 0 (a tough concept) to 4 (able to roll).

The method is zero-indexed and used to incorporate 0, 1, 2, 3 and 4. However there’s now a brand new stage — 2.7.

Here is a fast abstract of the brand new course of:

  • 0 — A brand new proposal (ideation and exploration).
  • 1 — The proposal is into account (characteristic design).
  • 2 — An settlement was discovered, and a potential resolution was outlined (refinement).
  • 2.7Checks are written (testing and validation).
  • 3 — The proposal is beneficial for implementation (integration and exploration of compat or integration points).
  • 4 — The brand new characteristic is able to be included within the spec and able to roll!

When did 2.7 present up? It is pretty new and was formalized on the finish of 2023. Here is Rob explaining why we would have liked a 2.7 stage.

Stage 2.7 is equal to what we used to name Stage 3. It signifies that the design is taken into account full, we now have a full specification, and we have to write code (checks and non-polyfill implementations) to achieve suggestions and make progress.

Stage 3 has been strengthened and now additionally signifies that test262 conformance checks are prepared.

If I get this proper, earlier than, stage 3 did not embody checks. The spec was written and agreed upon however points might nonetheless pop up when checks have been carried out. This might result in an surprising step again from stage 3 to 2.

With stage 2.7, there is a step in between, that means that if a proposal reaches state 3, everyone’s assured it will ship!

And why introduce an intermediate stage as a substitute of going from 0 to 5? The levels have been saved the identical as a result of altering them would lead to an excessive amount of linkrot and outdated docs. Consider the mess if 3 turned 4.

I do not know why they landed on 2.7, however seeing it makes me chuckle as a result of it appears so random.

Transitioning display types.

In spite of everything these years, it is potential to transition from and to show: none! How? With a mixture of @starting-style and transition-behavior. Kevin explains methods to do it.

Two boxes with background images and one has a gradient stacked on top of the background image.

I need to admit I do not perceive how and why this works, however apparently, you need to use a border-image to place one other layer between an outlined background and a component’s content material. 🤯 It is one line of CSS and ideal for stacking gradients to maintain issues readable.
