The iPhone’s portrait mode uses actual depth information captured from the separate depth sensor. The new feature is that it will always capture the depth information for every picture you take so that at a later point you can use it to blur parts of the image at different depths. Google’s version of portrait mode just uses image recognition to detect what’s in the background. It does a good job, but not as good as if it had actual depth information.

Just fyi, while they don’t help with running TS in the browser, the Bun and Deno runtimes both natively run TS without any compilation.
