Talk with a colleague about the reasons for the naming conventions we use:
.block
.block--element
.block.is-modifier
Why are elements preceded by a double dash?
Why is it important modifiers start with is or has…
Just like we use gems on the server, we use third party JavaScript libraries in the browser. These typically provide functionality like:
Take a look at the popular lodash library.
Understand all the terms in How Ruby method lookup works, in particular:

How does include and extend work together with inheritance?

In a web application you often need to move data between the client (HTML, Javascript) and the server (Ruby, Rails).
Add a find-as-you-type search to MovieDB. Above the list of movies there should be a text input that updates the list with the search results as the user is typing in the query. The user should not have to press a "Search" button (hint: you can bind to the [input](https://makandracards.com/makandra/33699-input-a-dom-event-that-is-fired-whenever-a-text-field-cha…
Movies in MovieDB should have one of the following workflow states:

Since the user interface makes up 70% of a typical web application, this is closely related to requirements analysis and cost estimation.
