Programming

After viewing the two videos, you should now be prepared to create your first program.

JavaScript is a scripting language. This simply means that the browser interprets each line of code before it is executed. A program language (like C# and Java) is compiled into assembly code (0's and 1's) before it is executed. However, the general syntax of JavaScript and other programming languages is very similar. Syntax is the structure (format) of the code, similar to the correct format used in creating a sentence.

We can create JavaScript code in a text editor (just like we did with the HTML code in the previous lab). In the Windows environment, Notepad can be used.

NOTE: Make sure that you use 'save as' and change the file type to 'all files' when saving HTML and/or JavaScript code. If you do not, the code will actually be saved as a text file and will not run in the browser (even if you did provide a file ending of html).

For this Lab, you are to create JavaScript code (similar to the videos) which will display the following when run in a browser.

"Hi my name is ????"

"I attend Chattahoochee Technical College"

"I am currently taking CIST 1001"

(Replace ???? with your KJUAN LEE)

The JavaScript code needed will be very similar to the code in the videos (except you need more than one print line). The code should also include the HTML statements shown in the videos.

Create the code in a text editor (notepad). After you have typed the code, use 'save as", change the file type to "all files". Now save the file as lab5.html.

If the file is saved properly, you should be able to double click the file and the code will run within your default browser.

If you see the code in the browser, and not the results of the code (the output from the print statements executing), then you may have not saved the file name correctly. Try saving the file again, as shown above.

If you see a blank page in your browser, or you see errors displayed, you have made syntax errors. Compare the code you typed in to the code shown in the videos. Pay special attention to the use of ';' at the end of the statements and the proper use of the "". Correct your mistakes and resave your file. Keep doing this until you get the expected results. It may take several times to get this correct. That is normal. Don't worry if someone else seems to do it quicker.

Hopefully, eventually, you will develop the correct code to produce the required output. If you still have problems, after many attempts, use the "CIST1001 - Questions about assignments and/or the class itself" discussion board to ask your teacher and fellow students for help.

Before submitting your file, reopen the file and add comments (inside the script tags as shown in the second video). The comments should include the following

KJUAN LEE

Spring2017

5/8/2017

Resave the file and run it one more time to make sure you did not mess anything up. You should not see the comments in the browser once you run the program. However, you should see the comments if you right click your web page, and select 'view source code'.

Once you are happy with the program, drop it in the drop box before the due date.
