Handlebars converts array of strings to array of variables

My problem is that when i send data to handlebars template it converts my array of strings to array of variables:

res.render('index', { 
  title: 'Express' ,
  chartT:"title",
  lab:['test','test2','test3'],
  dat:[1,3,5]
});

Template code:

  <canvas id="myChart" width="400" height="400"></canvas>
    <script>
      var pollOptions = [{{{lab}}}];
      var pollData = [{{{dat}}}];
      createChart("mychart",pollOptions,pollData);
    </script>

And the problem that in pollOptions i got this

var pollOptions = [test,test2,test3];

Uncaught ReferenceError: test is not defined

I don't know why the template convert them...

Thank you in advance for your help.

Ok I have figured it out!

var rawData = "{{{lab}}}";
var pollData = rawData.split(",");

And now i can use it as a string array

HandleBars dedicated to HTML templating (Not to render a JS variable) You can do something like this (Without handlebars): 

var pollOptions = ["{{{lab}}}"];
var pollData = ["{{{dat}}}"];
