Error Create Canvas not defined- While trying to save sample project - p5.js

I am trying to learn Java Script and I referring to Daniel Shiffman videos. I have installed Bracket and have downloaded the example project, On writing an implementation for setup and draw method I am getting the error [ERROR: createCanvas is not defined] in the ESLint(4) editor console.
I have attached the screenshot for reference.
referred the link (https://forum.processing.org/two/discussion/20819/getting-started-with-p5-js-using-brackets-having-problems) but that did not resolve my issue.
The video that I am looking in is https://www.youtube.com/watch?v=nmZbhManVcY
Update: When I click on Index.html it opens perfectly fine in the browser. The problem is only at the editor.
Index.html:
<!DOCTYPE html>
<html lang="">

<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

How do you reset the HTML cache in macOS Mail?

I'm developing an app that sends HTML mail. I just condensed all of my CSS code into a .css file that is now linked in the mail header:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<link href="https://example.com/mycss.css" rel="stylesheet">
</head>
<body class="email-body">
...etc...
I discovered a mistake in the .css file, re-uploaded it to example.com, and now for the life of me I can't get Mail to use it properly. Mail must still have the old .css file cached.
I know with Safari I can clear the cache with the Safari -> Clear History menu item. How do I do this in Mail?

some bug in FireFox polymer.dart | dart2js

Could you please help me to detect and fix same bug in the simple Click Counter application.
I generated the Click Counter application from Dart Editor (New project -> simple web application using polymer library..)
Now I want to add Social Likes functionality (see http://sapegin.github.io/social-likes/.)
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Sample app</title>
<!-- include the web_components polyfills with support for Dart. -->
<script src="packages/web_components/platform.js"></script>
<script src="packages/web_components/dart_support.js"></script>
<!-- import the click-counter -->
<link rel="import" href="clickcounter.html">
<link rel="stylesheet" href="cc.css">
<link rel="stylesheet" type="text/css" href="social-likes_birman.css" />
<script type="text/javascript" src="jquery-1.11.1.js"></script>
<script type="text/javascript" src="social-likes.min.js"></script>
</head>
<body>
<h1>Cc</h1>
<p>Hello world from Dart!</p>
<div id="sample_container_id">
<click-counter count="5"></click-counter>
</div>
<div class="social-likes">
<div class="facebook">Facebook</div>
<div class="twitter">Twitter</div>
<div class="plusone">Google+</div>
</div>
<!-- bootstrap polymer -->
<script type="application/dart">export 'package:polymer/init.dart';</script>
<script src="packages/browser/dart.js"></script>
</body>
</html>
This code works perfect in Dartium and Chrome, but doesn't work in Firefox (the styles of Social Likes is not applied! The web console of FireFox doesn't contain any error..
Dart Editor version 1.7.0.dev_04_06 (DEV)
Dart SDK version 1.7.0-dev.4.6
Firefox 33
The code of application is attached to this issue.
I really don't understand what is wrong. Is there a bug in FireFox or polymer or dart2js? This bug is very critical for me...
