Is there a difference between a function with and without a return statement?

Question

Say you have 2 identical functions that do not return a value

function a() {
    // do some interesting things
}

function b() {
    // do the same interesti         


        

Answer 1

Generally you are returning a value. So for instance,

function b() {
  return 'hello';
}

a = b();

console.log(a);

Will output "hello" to your console.
