| 1. Store a open index var | |
| 2. You can create other vars to hold html tags to be used in final formatting | |
| 3. Create the array. here we have one with 4 elements | |
| 4. evoke your for loop | |
| - I : create your sentry variable, use the same open index var you created | |
| at step 1. | |
| - C : While the index is less than the length property of fruits array, | |
| execute the block | |
| - U : And on each pass, update the index value. | |
| This is going to update the index continously, until the condition that | |
| the index is less than the array length is no longer true, then the loop exits. | |
| In the block itself, each pass we are prepending to var 'text' | |
| a list item tag, the value stored at the current referenced index, and | |
| a closing list itme tag. | |
| then we are going to concatenate the closing unordered list tag. | |
| now its ready to go, being output to the inner html of an element. | |

| <p>The best way to loop through an array is using a standard for loop:</p> | |
| <button onclick="myFunction()">Try it</button> | |
| <p id="demo"></p> | |
| <script> | |
| function myFunction() { | |
| var index; | |
| var text = "<ul>"; | |
| var fruits = ["Banana", "Orange", "Apple", "Mango"]; | |
| for (index = 0; index < fruits.length; index++) { | |
| text += "<li>" + fruits[index] + "</li>"; | |
| } | |
| text += "</ul>"; | |
| document.getElementById("demo").innerHTML = text; | |
| } | |
| </script> | |
| </body> | |
| </html> |
