The demonstration has checkboxes representing three colors. It also has two buttons, "Check All" and "Un-check All."
The checkboxes can be checked and unchecked individually. The two buttons cause all to be checked and all to be unchecked, respectively.
The JavaScript is two functions, CheckAll() and UnCheckAll().
When the "Check All" button is clicked, function CheckAll() checks all checkboxes. And when the "Un-check All" button is clicked, function UnCheckAll() unchecks all checkboxes.
