go: syscall/js: comparing two number objects with `==` fails

(This issue is copied from https://github.com/neelance/go/issues/27)

I’m using 8d6062b08b6d737f773d697e5dc52d98735b1194 on neelance’s wasm-wip branch

package main

import (
        "syscall/js"
)

func main() {
        n := js.Global.Get("Number")
        println(n.New(1) == n.New(1))
}

Shows false, I expected true though. I suggest == return true since it’d be more intuitive.

The current result might be intended, but was really confusing to me. For example, getting WebGL’s constant like FRAMEBUFFER_COMPLETE via Get creates a number object if I understand correctly, and comparing this constant value and another value always fails.

// gl is a WebGL context of a canvas.
if s := gl.Call("checkFramebufferStatus", gl.Get("FRAMEBUFFER")); s != gl.Get("FRAMEBUFFER_COMPLETE") {
        // This always comes here, whatever s is!
        return js.Null, errors.New(fmt.Sprintf("opengl: creating framebuffer failed: %d", s.Int()))
}

String object might be in the same situation .
