`Window`'s `self` property and `DedicatedWorkerGlobalScope`'s `name` property are defined as Web IDL read-only attributes with the `[Replaceable]` extended attribute, meaning that their setter will redefine the property as a data property with the set value, rather than changing some internal state. Deno currently defines them as read-only data properties instead. Given that Web IDL requires all attributes to be accessor properties rather than data properties, but Deno exposes almost all of those properties as either read-only or writable data properties, it makes sense to expose `[Replaceable]` properties as writable as well – as is already the case with `WindowOrWorkerGlobalScope`'s `performance` property. |

deno_runtime crate
This is a slim version of the Deno CLI which removes typescript integration and various tooling (like lint and doc). Basically only JavaScript execution with Deno's operating system bindings (ops).
Stability
This crate is built using battle-tested modules that were originally in deno
crate, however the API of this crate is subject to rapid and breaking changes.
MainWorker
The main API of this crate is MainWorker. MainWorker is a structure
encapsulating deno_core::JsRuntime with a set of ops used to implement Deno
namespace.
When creating a MainWorker implementors must call MainWorker::bootstrap to
prepare JS runtime for use.
MainWorker is highly configurable and allows to customize many of the
runtime's properties:
- module loading implementation
- error formatting
- support for source maps
- support for V8 inspector and Chrome Devtools debugger
- HTTP client user agent, CA certificate
- random number generator seed
Worker Web API
deno_runtime comes with support for Worker Web API. The Worker API is
implemented using WebWorker structure.
When creating a new instance of MainWorker implementors must provide a
callback function that is used when creating a new instance of Worker.
All WebWorker instances are descendents of MainWorker which is responsible
for setting up communication with child worker. Each WebWorker spawns a new OS
thread that is dedicated solely to that worker.
