How to use Handlebars ternary helper?

Handlebars helpers: http://handlebarsjs.com/#helpers don't follow the JavaScript syntax in the templates. You can use them like this:

<div>{{ternary true "yes" "no"}}</div>

Update 7/14/2017

Since both string are considered as truthy value in JavaScript, I have changed my code to the following:

{{input value=email placeholder="Enter Email" class="form-control"
    disabled=(if isResetting 1 0)
}}

How about trying to use inline if {{if}}?

{{if user.isAdmin "True" "False" }}

This worked for me, based on the documentation: https://handlebarsjs.com/guide/builtin-helpers.html#if

{{#each langs }}
    <a class="navbar-item {{#if active}}is-active{{else}}{{/if}}" href="#{{code}}">
        {{label}}
    </a>
{{/each}}
