What are some examples of eager loading in Sequelize?

Can you explain what eager loading is in Sequelize?

Eager loading in Sequelize is a technique to load associated models at the same time as the main model, reducing the number of queries.

Can you give me an example of how to implement eager loading?

Sure! You can use the include option in your query. For example: User.findAll({ include: [Post] }) loads users along with their posts.

What if I want to load multiple associations?

You can include multiple associations by passing an array to the include option, like this: User.findAll({ include: [Post, Profile] }).

Are there any performance considerations I should be aware of?

Yes, eager loading can improve performance by reducing the number of queries, but loading too many associations can lead to large data sets and slow responses.
