# Comments

Comments can be inserted in expressions.

You can use two types of comments:

* Single-line comments: the comment starts with // and ends with a new line.
  ```
  date = toDate('2021-04-08') //using function to cast string as date
  ```
* Multiple-lines comments: the comment starts with /\* and ends with \*/.
  ```
  /* this the first line in the comment
  this is another line in the same comment
  and this is the last line of the comment */
  ```
