| <h3><b>if</b> Helper</h3> | ||
| <hr /> | ||
| <p>You can use the 'if' helper to conditionally render a block.</p> | ||
| <p>If its argument returns false, undefined, null, "", 0, or [], Handlebars will not render the block.</p> | ||

| <p>Example: </p> | ||
| <pre> | ||
| <figure class="highlight"> | ||
| <pre class="code lang-json"> | ||
| { | ||
| author: { | ||

| } | ||
| </pre> | ||
| firstName: "John", | ||

| <h3>John Samuel</h3> | ||
| </div> | ||
| </pre> | ||
| </div></pre> | ||
| </figure> | ||
| <h3>output:</h3> | ||
| <h3>John Samuel</h3> | ||
| <p>When used with an empty ({}) context, author will be undefined, resulting in:</p> | ||

| <p>When using a block expression, you can specify a template section to run if the expression returns a falsy value. | ||
| The section, marked by \{{else}} is called an "else section". | ||
