Results ¶

• n is the count of bytes written.
• ok is false if the src was not a uint8Array.

See https://github.com/golang/go/blob/go1.20/src/syscall/js/js.go#L569 and https://github.com/golang/go/blob/go1.20/misc/wasm/wasm_exec.js#L437-L449

var CopyBytesToJS = goos.NewFunc(custom.NameSyscallCopyBytesToJS, copyBytesToJS)
