javascript async await arrow function code example

Example 1: async arrow function

const foo = async () => {
  // do something
}

Example 2: javascript async await arrow function

Async arrow functions look like this:

const foo = async () => {
  // do something
}
Async arrow functions look like this for a single argument passed to it:

const foo = async evt => {
  // do something with evt
}
Async arrow functions look like this for multiple arguments passed to it:

const foo = async (evt, callback) => {
  // do something with evt
  // return response with callback
}
The anonymous form works as well:

const foo = async function() {
  // do something
}
An async function declaration looks like this:

async function foo() {
  // do something
}
Using async function in a callback:

const foo = event.onCall(async () => {
  // do something
})
