title: Parsing a YAML file using js-yaml
body: <p>I am using js-yaml to parse and read the contents of a yaml file in node js, this is a typical key value pair yaml, 
   some of the keys in the Yaml have values in the format, example :</p>
  
  <pre><code>key : {{ val1 }} {{ val2 }}
  </code></pre>
  
  <p>The parsing is failing at such instances in the file. typically the error I get is:</p>
  
  <blockquote>
    <p>can not read an implicit mapping pair; a colon is missed at line X, column Y:\n</p>
  </blockquote>
  
  <p>what is the best way to parse the Yaml which has some key/values in the above format?</p>
