title: BackBoneJS: Why Internet Explorer does not accept the default parameter given to a function?
body: <p>I am using BackboneJS in my app. Below code works on google chrome but in IE (version 10) it gives syntax error in function parameter:</p>
  
  <pre><code>Syntax Error: Expected ')'
  </code></pre>
  
  <p>Below is my code:</p>
  
  <pre><code>initialize: function (options='default value') {
      console.log(options) 
  },
  </code></pre>
  
  <p>I have handled it by using if-else condition inside the function for default parameter, but I am  unable to understand the reason that why it is  working in chrome but not in IE 10 ?</p>
