How to access a query return

Question

I’m trying to add values using push, turns out it’s not working...

Only works inside the code block connection.query().

Is there any way to access variables and add values to them outside this scope?

My current code:

let customers = []

connection.query("SELECT * FROM customers", async (error, data) => {
  customers.push(data) // console.log(customers) aqui funciona
})

console.log(customers) // retorno => [] (vazio)
