Examples

Exclude Specific Status 

{{#if model.status != 'cancelled'}}
  <div class="order-active">
    <h3>Order #{{model.orderNumber}}</h3>
    <p>Status: {{model.status}}</p>
  </div>
{{/if}}

Data:

doc.Params["model"] = new {
    status = "pending",
    orderNumber = "12345"
};

Output:

<div class="order-active">
  <h3>Order #12345</h3>
  <p>Status: pending</p>
</div>

Check for Non-Zero 

{{#if model.balance != 0}}
  <p class="outstanding">Balance due: ${{format(model.balance, '0.00')}}</p>
{{/if}}

Filter Out Null Values 

{{#each model.users}}
  {{#if this.email != null}}
    <p>{{this.name}}: {{this.email}}</p>
  {{/if}}
{{/each}}

Highlight Changes 

{{#each model.items}}
  {{#if this.currentPrice != this.previousPrice}}
    <div class="price-changed">
      <span>{{this.name}}</span>
      <span class="old">${{this.previousPrice}}</span>
      <span class="new">${{this.currentPrice}}</span>
    </div>
  {{/if}}
{{/each}}

Show Alert for Specific Conditions 

{{#if model.stock != model.expectedStock}}
  <div class="alert-warning">
    <p>Stock discrepancy detected!</p>
    <p>Expected: {{model.expectedStock}}, Actual: {{model.stock}}</p>
  </div>
{{/if}}

Data:

doc.Params["model"] = new {
    stock = 47,
    expectedStock = 50
};

Output:

<div class="alert-warning">
  <p>Stock discrepancy detected!</p>
  <p>Expected: 50, Actual: 47</p>
</div>

Notes

  • Works with all data types (strings, numbers, booleans, objects)
  • String comparison is case-sensitive
  • For null checks, use value != null or null coalescing ??
  • Opposite of == (equality) operator
  • Commonly used with `` for conditional rendering
  • Can be combined with logical operators (&&, ||)
  • Type conversion may occur between compatible types
