You can use val() to get a JavaScript object with the entire set of data at the snapshot. Then you can iterate its keys using standard JavaScript object property iteration with for..in and break whenever you want.
const val = snapshot.val()
for (const key in val) {
console.log(`child key: ${key}`)
console.log(`child value: ${val[key]}`)
// break whenever you want
}
