Detecting that a value is an Object as opposed to an Array/Arguments/etc (or more generally, reading the StringTag of a value) still requires a toString.call(value) AFAIK. This is still used a lot in recursive polymorphic code lik

innerHTML has been slower than the DOM API for a few years. React had a big refactor at one point to rip out innerHTML logic precisely due to this. To make matters more interesting, the order of DOM API calls also mattered. In IE, building

The scale argument is really just a chicken-and-egg thing. A few years ago, people were saying the same thing about how Vue wasn't "proven" at scale. But these days there are sizable teams using Vue just fine. The entire poin

There's some nuance. DOM mutations are still expensive if you interpolate reading and writing operations. The declarative paradigm allows frameworks to batch same-type operations to prevent double repaints. This is the upsell of virtua

Interesting timing. Duolingo is a bit like Zoom in the sense that they got insane growth last year due to everyone being stuck at home. That should make the financial numbers look exceptionally good for IPO.

JIT compilers like V8 are able to optimize from Object hashmaps to structs, but the problem is that it has trouble figuring out how to group arbitrary object literals into the same bucket in order to get monomorphism guarantees (this is a v
