When I need to use a JSON-like object in JS with different data in each block and iterating through that object I make a HTML code via pug.
Let me describe it in code<
You can write the html tags as usually something like:
text: "wake up and <span class='color-red brush'>some teeth</span>"
Then in pug you can use unescaped attributes like this:
.some-class!=footerMenu.left[0].text
or using string interpolation attributes unescaped
.some-class !{footerMenu.left[0].text}
