If you haven’t worked with JavaScript in the last few years, these three points should give you enough knowledge to feel comfortable reading the React documentation:
- We define variables with
let
andconst
statements. For the purposes of the React documentation, you can consider them equivalent tovar
. - We use the
class
keyword to define JavaScript classes. There are two things worth remembering about them. Firstly, unlike with objects, you don't need to put commas between class method definitions. Secondly, unlike many other languages with classes, in JavaScript the value ofthis
in a method [depends on how it is called](https://developer.mozilla.org/en-US/docs/Web/Jav

When querying your database in Sequelize, you'll often want data associated with a particular model which isn't in the model's table directly. This data is usually typically associated through join tables (e.g. a 'hasMany' or 'belongsToMany' association), or a foreign key (e.g. a 'hasOne' or 'belongsTo' association).
When you query, you'll receive just the rows you've looked for. With eager loading, you'll also get any associated data. For some reason, I can never remember the proper way to do eager loading when writing my Sequelize queries. I've seen others struggle with the same thing.
Eager loading is confusing because the 'include' that is uses has unfamiliar fields is set in an array rather than just an object.
So let's go through the one query that's worth memorizing to handle your eager loading.
