How would you do this same example of passing a function into another function using arrow functions instead?

I don't get it, Guil was using arrow functions earlier in this track, but for this example he uses the old style of declaring function, so, its confusing me. I don't know how to use this same example in the video using arrow functions instead.

function say(something){
    console.log(something);
}

function exec(func, arg){
    func(arg);
}

exec(say, "hi, there");

Hey, would you mind pasting in the example code here? Thanks!

Let me know if this helps

const say  = something => {
    console.log(something);
}

const exec = (func, arg) => {
    func(arg);
}

exec(say, "hi, there");

Hello, there.

I know this is a old question, buy maybe you can still use this answer, or other students in the Community.

const exec = (func, arg) => func(arg); exec(something => console.log(something), 'Hi there')

That would work
