This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The crossOriginIsolated read-only property of the
WindowOrWorkerGlobalScope interface returns a boolean value that
indicates whether a SharedArrayBuffer can be sent via a
Window.postMessage() call.
This value is dependant on any Cross-Origin-Opener-Policy and
Cross-Origin-Embedder-Policy headers present in the response.
Syntax
var myCrossOriginIsolated = self.crossOriginIsolated; // or just crossOriginIsolated
Value
A boolean value
Examples
if(crossOriginIsolated) {
// Post SharedArrayBuffer
} else {
// Do something else
}
