I swear, folks and their JSX have me convinced they have Stockholm Syndrome. HTML+CSS in JS was always a pragmatic choice back in 2015, never the most elegant or most maintainable one. It's like the folks who refused to use anything bu

JSX. This was never zero cognitive overhead as compared to plain HTML. Folks have simply had 10 years of practice with their Stockholm Syndrome. With Svelte, you see a script tag with 99% plain JS, some HTML with some basic control and bind

I honestly don't believe you've actually used Svelte even in an experimental context to make such a comment. Go check out the tutorial on the Svelte site and get back to us. It's literally >90% just HTML, CSS, and JS. The

And there's the crux of it all. Nothing is pure in this world except perhaps some parts of math. Everything else is an approximation or a corruption. Point to any programming language that is supposed to be a pure example of anything a

Declarative: giving your order to the waiter and having the food returned to you fully prepared. SQL: describing the subsets of related data you want and not caring if that data is on disk, in memory, indexed, located on another server, or

And today's physicists will say that's a perfectly adequate approximation in your local frame of reference far below the speed of light. SQL describes WHAT data you want returned. A functional language describes HOW you retrieve t

3. Does the solution require more thought and library expertise to get the same task done? Compilers were a huge boon over hand-built machine code and assembly. In specific hot spots, someone can eke out better performance sometimes, but co

by ttfkam 4y ago
Are you calling a C compiler overhead as well? Ahead of time compilation is not runtime overhead, and for users of the web, runtime and network latency are all that matters with regard to the perception of speed.

Yep, Solid is among the fastest but requires more cognitive overhead. Svelte requires very little over and above HTML and JS while still being closer to Solid in performance than React, Vue, or Angular. And the latest interactions of React

Tell us you've never tried Svelte without actually saying you've never tried Svelte. You would have likely not said this if you had ever looked at Svelte-compiled JS. The amount of mutation is surprisingly small and easy to follow

innerHTML doesn't preserve event handlers. So you're either reassigning event handlers over and over or relying on delegate handlers everywhere. And while your statement makes intuitive sense regarding performance, actual measurem

Not that much slower than bigint as long as you replace the top one or two bytes in the UUID with a rotating per-minute counter. You keep 106 bits of entropy (from v4's 122 bits) while largely eliminating page faults. Walkability is el

Are you putting indexes on your temporary tables? Are you including the time it takes to create them? I can't speak for others, but most of my CTEs tend to be small enough where an index wouldn't help much. Of course toggling MATE

That's because Redshift doesn't support MATERIALIZED CTEs. In mainline Postgres, a MATERIALIZED CTE acts more like a temporary table with the performance characteristics you're looking for.

C++ is not object oriented; it's a multi-paradigm language that supports OO, generic, even some functional, etc. It is a schizophrenic beast that will go (and take you) in any direction you do and do not wish to go. For example, the ST

Reader is for text/characters while InputStream is for bytes. An InputStream always lays at the heart of a Reader. Java's I/O may not be the most elegant of simplest, but it makes additive sense assuming you don't just h

Almost 50 years ago in fact. And there were alternatives all along that timeline and many before it. SQL is the first and possibly the only successful fourth gen programming language, and the most substantive complaints generally boil down
