Isn't the least verbose way of writing the printDate() function as follows?
const printDate = date => console.log(date);
^since there is only one line of code in the function.
Your syntax shows:
const printDate = date => {
console.log(date);
}

231,248 PointsThere's a slight difference, the briefer form actually translates to this:
const printDate = date => {
return console.log(date);
}
But in this case there's no practical difference since "console.log" doesn't return anything.

1,762 Points@Steven Parker , I find this weird since in the video you're explicitly told about refactoring on arrow functions that have only 1 line of code in the code block .The syntax supports that it can be on 1 line and no curly brackets are needed.
When arrow functions have 1 parameter no parentheses are needed either.
So wouldn't the ultimate refactor be
const printDate = date => console.log(date);
It's seems to work fine when outputted in the console. I am just wondering if I am missing something here.

231,248 PointsIt works just fine, I was just pointing out that the equivalent conventional function would include a return.
But as I said, it's not important in this case since there's no value to return.

const printDate = date => console.log(date);
would be the finished version in the context of this exercise.
