Comments

Essential Question: How can I write comments in my project?

Mastery Objectives: 

• SWBAT write comments in their code.

• SWBAT comment out multiple sections of code for troubleshooting.

• SWBAT write multi-line comments in their code.

Do Now: Create the variable below.

console.log('It was love at first sight.');

console.log('The first time Yossarian saw the chaplain he fell madly in love with him.');

console.log('Yossarian was in the hospital with a pain in his liver that fell just short of being jaundice.');

console.log('The doctors were puzzled by the fact that it wasn\'t quite jaundice.');

console.log('If it became jaundice they could treat it.');

console.log('If it didn\'t become jaundice and went away they could discharge him.');

console.log('But this just being short of jaundice all the time confused them.');

Above is the beginning of the book Catch-22 by Joseph Heller.

1. On line 1, write a single line comment that says Opening line. Use // to create a single line comment.

Single line comments are great for adding context to your code. Multi-line comments are often best suited to prevent a block of code from running. However, both types of comments can be used for either purpose.

2. Use a multi-line comment so that the last 6 console.log() statements are all commented out.  The format is:

/* text goes here

*/

3. On the first line, write a single-line comment with the title of the book and the author.

4. At the bottom, write a knock-knock joke using multi-line comments.

5. Using a single-line comment, write your name on your code.

6. Run your program and take a screenshot and submit to google classroom.

Ticket-to-leave: In the comments below, write a single line comment and an multi-line comment.
