Well-known symbols

View Source 
var ErrVMUnwinding = errors.New("VM unwinding")

ErrVMUnwinding is a sentinel error that indicates the VM is unwinding with an exception. When this error is returned, the caller should abort and return vm.Undefined immediately (without returning an error) to let the exception continue to propagate.

Functions

func ObjectGetOwnPropertyDescriptorForHarness(obj vm.Value, name vm.Value) (vm.Value, error)

ObjectGetOwnPropertyDescriptorForHarness exposes a minimal descriptor getter for the test262 harness

func SetupTypedArrayPrototype 

func SetupTypedArrayPrototype(proto *vm.PlainObject, vmInstance *vm.VM)

SetupTypedArrayPrototype adds common TypedArray prototype methods to the given prototype object. This should be called after setting up the type-specific properties.
