* JDKJS:

* The easiest way to distinguish declaration vs. expression is the

position of the word function in the statement (not just a line,

but a distinct statement). If function is the very first thing in

the statement, then it’s a function declaration. Otherwise, it’s a

function expression

* */

// Example 120 - Function Declaration vs Expression

// this is a function declaration

function printHello() {

console.log("Hello");

}

// this is a function expression, because 'function' is not the very first thing in the statement

(function printHelloWorld() {

console.log("Hello World");

})();
