# Having a go with JsEden

Firstly let's try using the EDEN translator. Try:

    greeting = "Hello";
    subject = "World";
    sentence is greeting // ", " // subject // "!";

Now let's try the raw JavaScript API:

    root.lookup('greeting').assign("Goodbye");

It's possible to look at the various meta-data stored for the 'sentence' symbol by missing off the call to `value()`
