Comment by Mev-Rael on "Does Angular ship with a Virtual DOM, like React?"

React has a VirtualDOM which arguably make is performant.

Who told you that? It is not true. In very, very few cases with extra large set of data to be rendered instantly (what is a huge mistake already because average user reaction is 300ms and screen physical size is very limited, rendering thousand of rows, which is impossible to display to user at the same time, are not needed, it is just a waste of resources) you may see a very small performance comparing to Vanilla JS, however, Vanilla JS implementation in such tests should be better and then, of course, in 100% case Vanilla JS is a fastest approach using minimum memory.

Absolutely contrary - virtual DOM is a waste for performance and moreover - it eats memory.

does Angular have a Virtual DOM

No, because it is not needed, it is only the waste of time and resources, and it just adds an extra complexity. Virtual DOM is Facebook's virtual problem which was very good marketed. People believe Facebook's fake news very often.

If it doesn’t, do yo think Angular should ship with a Virtual DOM?

Of course, no.

Also - Angular is dead. Use JavaScript or Vue/React at least.

Incorrect. Virtual DOM is generally performant. They wouldn't have gone through the trouble of making it if there weren't a reason for it. auth0.com/blog/updated-and-improved-more-benchmar… Yes it takes up more RAM but that's the point and how caching works.

I think it is generally accepted that a virtual dom makes rendering performant. I think the idea is that it is way faster to compute the difference between UI states and efficiently change it in the optimum way instead of requiring a rerender of the entire scene.

Curious why anyone would think Angular is dead? Version 7 just came out like 2 months ago...

I would agree, AngularJS (1.x) is pretty antiquated, but there are a lot of companies still using that as well, so there still is a lot of use in that system.

Oh, unless you're just trolling to get someone to bite...

...fascinating that someone would suggest "use JavaScript" in place of Angular.... when AngularJS is in JavaScript.... and Angular2+ is in TypeScript, which is essentially JavaScript with some added bells and whistles.
