title: How to fix JSON indentation in vim?
body: <p>In vim, the default indentation for JSON is:</p>
  
  <pre><code>{
      "employees": [
      { "firstName":"John" , "lastName":"Doe" }, 
      { "firstName":"Anna" , "lastName":"Smith" }, 
      { "firstName":"Peter" , "lastName":"Jones" }
      ]
  }
  </code></pre>
  
  <p>But what I expect is:</p>
  
  <pre><code>{
      "employees": [
          { "firstName":"John" , "lastName":"Doe" }, 
          { "firstName":"Anna" , "lastName":"Smith" }, 
          { "firstName":"Peter" , "lastName":"Jones" }
      ]
  }
  </code></pre>
  
  <p>I did google and tried some vim-json plugins, but none of them fix this issue. </p>
