Sometimes, you may have repeated HTML on your handlebars template. In those cases, you can create and register a new helper, that can be invoked from hbs templeate.

Gost: Ghost it a blogging platform developer on the top of express framework of nodejs.

EmberJs: Ember js is a javascript framework, same as angular.js.

So, here I am going to tell you how to create a helper in ghost ember and handlebar.

check-equality.js:

Create a new file "check-equality" and place it inside "/core/client/app/helper/".

Code:-

import {helper} from 'ember-helper';

export default helper(function (value) { //Value is an array: [1,10]
    var actual = value[0];
    var expected = value[1];
    return actual === expected;
});

How to use the check-equality helper in handlebars template (edit.hbs) file:

{{check-equality 1 10}} // Returns: false
{{check-equality 10 10}} // Returns: true
{{check-equality 20 10}} // Returns: false
{{check-equality 20 20}} // Returns: true

It can also be used to check certain condition for example:

{{#if (check-equality 1 10)}}
    both numbers are equal
{{else}}
    both are unequal
{{/if}}

Result:

both are unequal
