Declare function with property in one statement? [duplicate]

Question

I know that I can create a function:

const fn = () => {}

And I know that I can attach a property to it:

fn.a = 'a'

Can I use some kind of object literal syntax to do what I did above in one statement?

I'm thinking something along the lines of:

const fn = {
  (): {},
  a: 'a'
}

Answer 1

You could do it in one statement like this.

const fn = Object.assign(() => {}, { a: 'a' });
