(This, incidentally, is why the current 'zero-config' marketing fad is such nonsense: it really means 'abdicate the responsibility for config'. Instead of a single place where you can view all the build config in a structured, coherent form, you have the exact same amount of config but scattered around your project in lots of annoying files that are harder to understand.)

With the caveat that hero worship can be gross, distorting, and unhelpful to everyone involved, Svelte author Rich Harris (@rich_harris on Twitter) is one of my favorite open source developers. In the JS community he’s well-known among tool authors for spreading interesting ideas. He’s the creator of many open source projects including Rollup, the bundler of choice for many libraries including React and Vue.

He is best known for developing: Ractive, a template-driven UI library Rollup, a module bundler Bublé, an ES2015 compiler With Svelte, Rich Harris is not at his first attempt at creating a JavaScript library.

Almost a year after the release of its version 3, Svelte continues to make people talk. Rich Harris, especially through his communication, is obviously the main architect of this.

Thanks for the PR @RedHatter. I think it's important to be able to specify which warnings are being disabled, and I'm nervous about the use of the code frame for this sort of thing (feels brittle), so I've opened a new PR, #3351. Will close this in favour of that

Long ago, the standards deities gifted us <style scoped>, before removing it in favour of the arguably less-useful shadow DOM encapsulation mechanism.

Virtual DOM is valuable because it allows you to build apps without thinking about state transitions, with performance that is generally good enough

However, it does seem that objects can change over time. If one were to look at a tree one day, and the tree later lost a leaf, it would seem that one could still be looking at that same tree.

It could be nothing more than my mind coming up with ways to justify the absence of variable declarations, because the thought of implementing them scares me.
