// Module 4 Assignment Instructions.
//
// The idea of this assignment is to take an existing array of names
// and then output either Hello 'Name' or Good Bye 'Name' to the console.
// The program should say "Hello" to any name except names that start with a "J"
// or "j", otherwise, the program should say "Good Bye". 

// STEP 1:
// Wrap the entire contents of script.js inside of an IIFE
// See Lecture 52, part 2
// (Note, Step 2 will be done in the SpeakHello.js file.)

( function () {
		var names = ["Yaakov", "John", "Jen", "Jason", "Paul", "Frank", "Larry", "Paula", "Laura", "Jim"];

		// STEP 10:
		// Loop over the names array and say either 'Hello' or "Good Bye"
		// using the 'speak' method or either helloSpeaker's or byeSpeaker's
		// 'speak' method.
		// See Lecture 50, part 1
		for (var i = 0; i < names.length; i++) {

		  // STEP 11:
		  // Retrieve the first letter of the current name in the loop.
		  // Use the string object's 'charAt' function. Since we are looking for
		  // names that start with either upper case or lower case 'J'/'j', call
		  // string object's 'toLowerCase' method on the result so we can compare
		  // to lower case character 'j' afterwards.
		  // Look up these methods on Mozilla Developer Network web site if needed.
		  var firstLetter = names[i].charAt(0).toLowerCase();

		  // STEP 12:
		  // Compare the 'firstLetter' retrieved in STEP 11 to lower case
		  // 'j'. If the same, call byeSpeaker's 'speak' method with the current name
		  // in the loop. Otherwise, call helloSpeaker's 'speak' method with the current
		  // name in the loop.
		  if (firstLetter === 'j') {
		    // byeSpeaker.xxxx
		    byeSpeaker.speak(names[i]);
		  } else {
		    // helloSpeaker.xxxx
		    helloSpeaker.speak(names[i]);
		  }
		}
