In the previous exercises, you’ve mostly worked with individual expressions, however, you have the ability to combine expressions! In this exercise, you will combine the {{if}} block and the {{each}} block together in a single <script>!

Let’s revisit the code from the previous exercise. In this exercise, you’ll be adding an element to the languages array and adding a new property, modern, to all the elements. Then you will manipulate the Handlebars script to show different texts based on the modern property.

Instructions

1.

In main.js, add a modern property with a value of true to each element of the languages array.

2.

Now, add another object to the array in the languages property of context. This object will have a name property with a value of 'COBOL' and a modern property of false.

If you take a look at the web page, you’ll see that you should learn every language. But, since ‘COBOL’ isn’t a modern language maybe it should be given less priority. Let’s change that in the next step.

3.

Navigate to index.html, in the Handlebars <script>, add a starting {{if}} expression directly under the <div class="card">. Add an argument of this.modern to the starting {{if}} expression.

Then, directly above the closing <div> tag, add the closing {{if}} expression.

4.

Great, now you should see that ‘COBOL’ is no longer on the web page!

But remember, you can use {{else}} to create a default behavior for when languages are not modern.

In the Handlebars <script> element, add an {{else}} section to the {{if}} block. Inside the {{else}} section, add a paragraph element that has the text When I have time, I'll learn {{this.name}}.

Now you’ve covered both cases when the language is modern and when it isn’t!
