Comments in Apps Script

You can add comments to your code to help others understand what your code does. Apps Script will ignore comments so your program's output will not change because of comments.

Single line comments

These are used to add short, one-line comments. Use two forward slashes (//) to add a single-line comment. Apps Script will ignore all the text following // on the same line.

// This is a single-line comment.
let maxPrice = $1000; //max price was decided by John Raymond (VP sales)

Multi-line comments

These are used to add more detailed comments in your code. As the name suggests, these can span multiple lines.

Use a forward slash and an asterisk (/*) to start a multi-line comment and an asterisk and forward slash (*/) to end it. Apps Script will ignore the text in-between /* and */.

/*
