Is there an option to and/or how do I suppress errors like the following?
175,14:[\'tracker\'] is better written in dot notation.
I assume you are asking about Dreamweaver or another editor.
Dreamweaver
You may go to Edit -> Preferences -> Linting
Select JS in the dropdown and hit Edit & Apply changes
Find
"sub": false,
and change that to true. Save the file and that notice will disappear.
If you have OTHER Linting things you wish to edit, you can find a helpful list of them all at https://jshint.com/docs/options/
