Another helper that Handlebars offers is the {{each}} block which allows you to iterate through an array. Just like the {{if}} block, there is an opening {{#each}} expression and closing {{/each}} expression. Inside the {{each}} block, {{this}} acts as a placeholder for the element in the iteration.

Below is an example of the Handlebars {{each}} block:

{{#each someArray}} <p>{{this}} is the current element!</p> {{/each}}

This {{each}} block would be paired with an array like:

const context = { someArray: ['First', 'Second', 'Third'] }

After compiling, the HTML will look like:

<p>First is the current element!</p> <p>Second is the current element!</p> <p>Third is the current element!</p>

In this exercise, you’ll be writing your own {{each}} block and using the {{this}} expression.



In index.html, in the <script> element with an id of eachHelper, create an {{each}} helper block. Use {{#each}} to start the block and {{/each}} to end the block. Add an argument of newArray to the starting expression.


Inside the {{each}} block, add a <div> element with a class attribute of "block". The content of the <div> will be {{this}}.

Before you run the code, navigate to main.js and find the newArray property of the context object.

Notice that the newArray property contains an array of the letters 'a', 'b', and 'c'.

Run your code. If all went well you’ll now have 3 blocks on the webpage!


Just to showcase how useful {{this}} and {{each}} can be, delete the elements inside the newArray. Instead of letters, filled array with elements of numbers starting with 1 and ending in 10.

Run your code. This time, if all went well, your letters will be replaced with 10 blocks that increase from 1 to 10!
