Tricky async declarations

Imagine the following code, using Express and Sequelize:

app.get('/', async (_, res) => { const result = await sequelizeModel.getStuff()[0] return res.status(200).send(result) } 

In simple words: given an endpoint, it will execute a query on the database and return the result.

But there's a small gotcha: that code works but doesn't return the results, because at the time of the promise creation, the [0] is not available/ready.

Only after the promise/async is fulfilled, the Sequelize object exists.

Working code:

app.get('/', async (_, res) => { const result = await sequelizeModel.getStuff() return res.status(200).send(result[0]) }
