Comments

You can write additional notes to help you think through problems in JavaScript. To write these additional notes, you use comments.

Comments appear in two forms:

1. //
2. /* */

Commenting with //

You can write comments in JavaScript by adding double slashes (//). Anything after // is commented and will not be run by JavaScript.

// This is a comment

You can write // comments anywhere in your code, even in the middle of a line, like this:

const tables = 4 // 4 tables in the room

For the purpose of this course, whenever I console.log a variable from this point onwards, I would also write a comment that shows you what is printed in the console, like this:

console.log(44) // 44

Commenting with /* */

You can also write comments with the /* */ syntax. Any words between /* and */ is a comment.

/* This is a comment */

You can write comments that span multiple lines if you use /* */:

/*
  Everything
  is
  commented
  in
  this
  example.
*/
