title: Handlebars output all fields in iteration with exclusions
body: <p>If I have the following json:</p>
  
  <pre><code>{
      "a": 1,
      "b": 2,
      "c": 3,
      "d": 4,
      "e": 5,
  }
  </code></pre>
  
  <p>I would like to output all of the json fields into HTML:</p>
  
  <pre><code>&lt;div&gt;
  {{#each this}}
      &lt;p&gt;{{@key}} - {{this}}&lt;/p&gt;
  {{/each}}
  &lt;/div&gt;
  </code></pre>
  
  <p>This would output the following:</p>
  
  <pre><code>&lt;div&gt;
      &lt;p&gt;a - 1&lt;/p&gt;
      &lt;p&gt;b - 2&lt;/p&gt;
      &lt;p&gt;c - 3&lt;/p&gt;
      &lt;p&gt;d - 4&lt;/p&gt;
      &lt;p&gt;e - 5&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>However, how could I use this loop to exclude the field <code>c</code> from the iteration:</p>
  
  <pre><code>&lt;div&gt;
  {{#each this}}
      {{#if key does not equal 'c'}}
          &lt;p&gt;{{@key}} - {{this}}&lt;/p&gt;
      {{#if key does not equal 'c'}}
  {{/each}}
  &lt;/div&gt;
  </code></pre>
  
  <p>Such that the output is:</p>
  
  <pre><code>&lt;div&gt;
      &lt;p&gt;a - 1&lt;/p&gt;
      &lt;p&gt;b - 2&lt;/p&gt;
      &lt;p&gt;d - 4&lt;/p&gt;
      &lt;p&gt;e - 5&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How can this be achieved using Handlebars.js?</p>
