 Create different functions, both functions that return something and functions that don't return anything.
 
+#1 returns random number 1 -100
+function randomNumber(){
+    return Math.floor(Math.random() * 100) + 1;
+}
+randomNumber(); 
+
+#2 does not return anything
+function randomNumber(){
+}
+randomNumber(); 
+
 See if you can create a function that has a mix of parameters and parameters with default values.
 
+#1
+function greet(firstName, lastName){
+    return `Hey there, ${firstName} ${lastName}`;
+}
+greet('Boboye', 'Andazi');
+
+#2
+function greet(firstName, lastName = 'Ford'){
+    return `Hey there, ${firstName} ${lastName}`;
+}
+greet('Boboye');
+greet('Boboye', 'Manny');
