Of course, there's a lot more that you can do than just this! Handlebars also supports conditional statements:
let model = { name: 'World', description: 'This will only appear because its set.' }; <div> Hello {{ name }}!<br/><br/> {{#if description}} <p>{{description}}</p> {{/if}} </div>
Using an if block helper, as shown in the preceding code, you can check for true conditionals and only display HTML and/or data if the condition is true. Alternatively, you can use the unless helper to do the opposite and display HTML only if a condition is false:
let model = { name: 'World' }; <div> Hello {{ name }}!<br/><br/> {{#unless description}} <p>NOTE: no description found.</p> {{/if}} </div>
You can use both if and else as well as unless the same way you would use conditional if/else in other programming languages. So that's it! These were all the basics that we need to know to resume our application.
