title: type="text/ecmascript" vs type="text/javascript"
body: <p>I was reading a book about learning JavaScript, and there was these paragraphs:</p>
  
  <blockquote>
    <p>...in middle of 1997, Microsoft  and Netscape, with associate of 
    European Computer Manufactures Association,<br><br> released the first
    version of a standard that named <code>ECMAScript</code> or with official form
    <code>ECMA-262</code>...</p>
  </blockquote>
  
  <p>As much as I was found in this book and something like this, JavaScript and ECMAScript are the same and are different just in name.</p>
  
  <p>From other hand, in Dreamweaver, bracket, and some other editors, there's some autocomplete suggestion like this:</p>

  <p>when I want to add a script tag to my page.</p>
  
  <p>I want to know if there are differences between <code>ECMAScript</code> and <code>Javascript</code> and when should I use <code>text/javascript</code> or <code>text/ecmascript</code>?</p>
