I'd like to be able to use the cool es6 classes feature of nodejs 4.1.2
I created the following project:
a.js:
class a {
constructor(test) {
a.test=test;
}
}
index.js:
require('./a.js');
var b = new a(5);
as you can see I create a simple class that it's constructor gets a parameter. and in my include i require that class and create a new object based on that class. pretty simple.. but still i'm getting the following error:
SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode
at exports.runInThisContext (vm.js:53:16)

any ideas why ?

Finally es6 classes have landed in Node.
Lots of people don't know it, but you can use and extend real classes in Node. js already. There's a few drawbacks, but once you learn about them, they're really not drawbacks but postive things, that will make your code faster and better.
ES6 classes are syntactic sugar for the prototypical class system we use today. They make your code more concise and self-documenting, which is reason enough to use them (in my opinion).
Or you can run like this:
node --use_strict index.js
