Is there anyway to check condition with a variable?

[happyduong]

I have a categories array:

"categories": [
    {
      "id": "22",
      "name": "Brands",
      "url": "/brand/"
    },
    {
      "id": "1",
      "name": "Women",
      "url": "/women/"
      }
}

And i have a setting variable:
"category_id": "1"

in HTML:

{{#each categories}}
     {{#if id '==' '1'}}
          <a href="{{url}}">{{name}}</a>
     {{/if}}
{{/each}}

OUTPUT:
<a href="/women/">Women</a>
==> This is correctly output.

BUT WHEN I USING category_id VARIABLE:

{{#each categories}}
     {{#if id '==' category_id}}
          <a href="{{url}}">{{name}}</a>
     {{/if}}
{{/each}}

==> It's not working. :((

So my question is: Is there anyway to check condition with a variable?

The {{#if}}-helper only checks for truthy values and it takes only one argument. If you want to compare things, you need to register your own helper: Have a look at #206 for examples on how to achieve this.
