Really not React in 33 lines at all.

https://github.com/leontrolski/leontrolski.github.io/blob/ma... captures the spirit of React.

The "diff & patch" pattern is super common, e.g. Git and Incremental by Jane Street: https://github.com/janestreet/incremental

And curses!

> The programmer sets up the desired appearance of each window, then tells the curses package to update the screen. The library determines a minimal set of changes that are needed to update the display and then executes these using the terminal's specific capabilities and control sequences.

The submitted title was "React in 33 lines". We've since changed it. This is a case where rewriting the title did the article a disservice. To my ear there is a subtle but significant difference between that and "33 line React", which is what the author actually said.

"React in 33 lines" sounds reductionist. With the actual title, there's an implicit "a" (i.e. an indefinite article) at the start, i.e. "A 33-line React". In other words: a short exercise exploring the core idea of React. Not a claim of total equivalence.

Submitters: please read the site guidelines. They include "Please use the original title, unless it is misleading or linkbait; don't editorialize." Much of the time, when people rewrite a title, they make it more misleading or linkbait, even if they didn't mean to.

Care to elaborate?

It's a very, very minimal implementation. The diff algorithm they use does not really have the necessary optimizations implemented.

Not all applications have a requirement around "necessary optimizations". Sometimes if the application is simple enough, something like this submission could be good enough.

Or the constraints could be different where the bundle size vs performance implications could be worth trading.

Depends on context :)

You seem to be talking about something else. We're talking about how this library is not React in 33 lines. It could be better labelled as a "VDOM framework in 33 lines".
