0.23.0

Breaking changes

• Drop Swift 5.10 and earlier supports
• JSValue no longer conforms Sendable nor Error
• JSError no longer conforms Sendable nor Error

See #286 for rationale of removal of Sendable conformance from JSValue

Added APIs

• JSException type is added to replace usage of Error conformance of JSValue
• JSSending type is added to provide a way to safely transfer or clone JavaScript objects between threads

Quick example of JSSending

// Transfer an object to another thread
let buffer = JSObject.global.Uint8Array.function!.new(100).buffer.object!
let transferring = JSSending.transfer(buffer)

// Receive the object on a worker thread
let executor = try await WebWorkerTaskExecutor(numberOfThreads: 1)
Task(executorPreference: executor) {
    let receivedBuffer = try await transferring.receive()
    // Use the received buffer
}

// Clone an object for use in another thread
let object = JSObject.global.Object.function!.new()
object["test"] = "Hello, World!"
let cloning = JSSending(object)

Task(executorPreference: executor) {
    let receivedObject = try await cloning.receive()
    // Use the received object
}
