How to write multiple lines of code in Node REPL

Question

I would like to evaluate

var foo = \"foo\";
console.log(foo);

as a block, instead of evaluating line by line

var foo = \"f

Node v6.4 has an editor mode. At the repl prompt type .editor and you can input multiple lines.

example

$ node                                                                                                   
> .editor
// Entering editor mode (^D to finish, ^C to cancel)
const fn = there => `why hello ${there}`;
fn('multiline');
// hit ^D 
'why hello multiline'
> // 'block' gets evaluated and back in single line mode.
