Service workers are threads. They’re basically separate JavaScript processes you communicate with with IPC, with other special privileges and capabilities allotted to them.

Edit: also, if an attacker dumps all the data today then loses access to the data tomorrow, having access to my password hashes means they can access my account and data later.

This comment is an example of why I wouldn’t want any given website to choose my password.

I was misunderstanding your point with the deserialize.

Edit: “using” -> “uses”

The correct type for values you don’t know the type of (like the response of an API call) is “unknown”.

TypeScript does not provide the facilities you describe because there is not a one-size-fits-all solution to the cases that are possible and common in JavaScript.

It is left to the developer to decide how to validate unknown data at the boundaries of the API.

There are third party libraries that facilitate this in different ways with different trade-offs.

  The compiler actively lies to you about the types you’ll have at runtime.

  In nearly any other typed language I have some deserialization mechanism.

This is not meant as an argument against what you’re saying, because I know you were just giving an example, but I found this and thought you may find it interesting: https://www.hacklewayne.com/a-truly-strongly-typed-printf-in...

  You're forced to emulate exactness by always destructuring objects - not great.

Edit:

  Non-goals:
  …
  5. Add or rely on run-time type information in programs, or emit different code based on the results of the type system. Instead, encourage programming patterns that do not require run-time metadata.

    Also you should fill your database with houses - use AI or some sort of random data generator to generate them and just make sure there's a small but clear note on the listing saying this is AI data. It's not ideal but it is better than an empty database. Give people something to look at.

In the movie, they of course have the technology to do these things, but it’s usually used for “extraction”: stealing information and ideas from one’s subconscious by infiltrating their dreams.

“Inception”, as used in the movie, is just the opposite of “extraction”: to plant an idea in someone’s subconscious by infiltrating their dreams.

So while I think it’s a stretch, it’s not as bad as suggesting that people can commingle in dreams.
