How do I return a value from a javascript function

Question

Say I have a function

function myFunction(myValue) {

    // do something

}

How would I return a value from this, say a string type after the method is executed?

Answer 1

Use the return statement, just like you would with any other JavaScript function:

return "Hello";

Also, JavaScript is dynamically typed so you don't have to specify a type for the function, just return the variable.

Answer 2

function myFunction(myValue) {
  // do something

  // return to caller of function:
  return myValue;
}

var result = myFunction(myValue);
