Are JsValue.Call and JsValue.Invoke meant to keep/change scoped variables?

[scarletquasar]

Supposing I make that code:

function scopedBlock() {
    let a = 1;
    const b = () => a = 2;
    _callSomeBindingWithInvoke(b);
   return a;
}

And the _callSomeBindingWithInvoke code behind is:

void CallSomeBindingWithInvoke(JsValue value) {
    value.Invoke();
}

What is the supposed value of a after the function return? Currently, Its not keeping the scope (on my usage) but I want to know if that is the objective. Same for Call().

This test case passes as green so I guess it works?

[Fact]
public void TestScopedAccess()
{
    var engine = new Engine();
    engine.Execute(@"function scopedBlock() {
let a = 1;
const b = () => a = 2;
_callSomeBindingWithInvoke(b);
return a;
}");
    engine.SetValue("_callSomeBindingWithInvoke", new Action<JsValue>(value =>
    {
        value.Invoke(_engine);
    }));

    var result = engine.Evaluate("scopedBlock()");
    Assert.Equal(2, result);
}

Based on the value.Invoke() call without engine parameter, I'm guessing it's Jint 2.x?

No, Im using the latest Jint version
