Hi,

The following code works as expected:

> var context = { Array: Array };
undefined
> vm.runInNewContext("var a = new Array();", context)
undefined
> context.a instanceof Array
true
> 

However, when Array is replaced with an array literal the instanceof assertion fails:

> vm.runInNewContext("var a = [];", context)
undefined
> context.a instanceof Array
false

Due to dependent library reasons we are currently running node version 0.10.33.

Is this a bug or is there a way around this?

Thanks.

Edit:

The assertion Array.isArray(context.a); returns true for both cases, but I'd like to know why the instanceof is failing
