Incompatibility with ECMA6

[sinner]

You can't use it if your javascript files have ECMAScript 6 templating with "`" character like

var name = 'Joe';
var message = `<div class="alert alert-info"> Hello ${name}</div>`;

The code generated now is:

var a='Joe';var b=`<div; class="alert alert-info"> Hello ${name}</div>`;;;
