Arrow function syntax related to keyword return.

Is it true that removing curly braces when there is only one line of code in the function will always result in the browser interpreting that as a return, or implying a return? Could that possibly lead to any problems to look out for? For example, what you are saying is

const printDate = date = () => console.log(date); //this is "techinacally" still 'returning' the console.log(date);

const printDate = date = () => {console.log(date)}; //this is just running console.log(date); with no implied return

const printDate = date = () => {return console.log(date)} //would this break?;

actually the bottom 2 will break as you are forgetting a closing parenthesis on the closing of console.log :)

Yes, that is totally fine. Only works with arrow functions.
