The Truth About The New Javascript Proposal

The New TC39 Proposal for Standardizing Signals Into Javascript & ECMAScript could change javascript forever and how we build user interfaces forever as we know it. But did you know that Signals were introduced nearly 15 years ago, in 2010. The Framework is called Knockout js.

Hi I wanna add an e-commerce store app for my portfolio. I wonder which react stack is solid for it in 2024. Can someone suggest something? As a back I would prefer Firebase, also for styling scss+mui but need recommendations about state manager and other technologies and tools. Thanks!

Amazing content, just a doubt : isn t innerText bad?

new era of modern vanillajs

I think you miss understand the computed it is easier than you explained it is just memorized function when you re-evalute it will re-run it is not magically listen to changes, this even mentioned in the pr “Lazy Evaluation - Computations are not eagerly evaluated when they are declared, nor are they immediately evaluated when their dependencies change. They are only evaluated when their value is explicitly requested.” It is like useMemo and useCallback in react, but there is another problem react does not listen to changes and change things based on them it just re-render this mean re-evalute the component that is why react team suggest useMemo and useCallback and memo and yes react have implemented the unit of work pattern under the hood but at the end react is not reactive framework

But how we can try signals like you in this video

[@CoderOne]

install signal-polyfill and you can use it in your javascript project

[@brayanyevenes5954]

i don't know why but when i look at signals jotai comes to mind

[@juanmacias5922]

Solid.js was my first intro to them. :D

How this wil replace vue it's literally the same as vue's reactivity model

[@headsofhiphop]

Feels too similar to react too. I don't see a lot of benefit to this
