Calling JavaScript from Go

Load a script that defines functions, then drive it from Go: fetch a function global, call it with converted arguments, and read the result back.

go run ./examples/call_js

Expected output:

Hello, world!
stats: map[count:4 mean:5 total:20]

Key points:

• vm.GetGlobal(name) fetches a value (e.g. a function) defined by the script.
• vm.Call(fn, this, args...) invokes a callable JS value from Go. Pass gojs.Undefined for this unless calling a method.
• Convert across the boundary with vm.FromGo (Go → JS) and vm.ToGo / vm.ToString (JS → Go).
