You must declare function first, otherwise, it won't work.

const greet = (val) => { return Hi, ${val}!; }

greet('cool coders');

Exactly as Denis mentioned. If you create a function declaration then it does not matter if you call the function before or after initialization. It will work. However, in case of an arrow function or a function expression the function initialization has to be before the call otherwise the console throws an error and it won't work.

I tried to run this in JS console and got the following message. What is this wrong?

const greet= (val)=> {return Hi, ${val}!;}

greet('cool coders'); VM34:1 Uncaught SyntaxError: Unexpected token '{'

Hi, you apparently omitted the quotation marks. Try this:

const greet = (val) => {
return `Hi, ${val}!`;
}
greet('cool coders');

You are probably missing backticks ``

const greet = (val) => {
    return `Hi, ${val}!`;
}
greet('cool coders');
