How to Throw an Error From the Golang Function

[gastraight]

Hi!
While injecting a golang function into a js runtime how to throw an error js way within this function
e.g.

	runtime := goja.New()
	runtime.Set("aFunc", func() {
               // how to throw an error here
        })
        runtime.RunString(`
              try {
                  aFunc()
              } catch (error) {
                  // so that to be able to catch it over here 
             }
        `)

Thx.

runtime = goja.New()
runtime.Set("Read", func (path) {
	data, err := os.ReadFile(path)
	if err != nil {
		panic(runtime.ToValue(err))
	}

	return string(data)
})

runtime.RunString(`
	try {
		Read("test")
	} catch (err) {
		console.log(err)
	}
`)

hi @gastraight you can use this example to throw error from golang to the vm

here panic(runtime.ToValue(err)) is important (it dosen't crash the go program) if you do panic(err) then the go program crashes
