How do I return a value from a javascript function

Say I have a function

function myFunction(myValue) {

    // do something

}

How would I return a value from t开发者_JAVA百科his, say a string type after the method is executed?

Use the return statement:

return "Hello";

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

function myFunction(myValue) {
  // do something

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

var result = myFunction(myValue);
