Jade render an array of strings as an array of string

Question

I'm passing data to render template:

res.render 'index', {data: ['a', 'b']}, function(err, html) {
});

in the template, I'd like to render the array ['a', 'b'] as an array in javascript:

script(type='text/javascript').
  var arr = #{data};

but they are rendered as [a, b], an array of variables, what I want is variable names: ['a', 'b'].

Thanks

First you need to JSON.stringify the data property object.

...
data: JSON.stringify(['a', 'b'])
...

Then in your Jade Template use !{}.

var arr = !{data}; // ["a","b"];
