Can anyone help with checkboxes in angular?

Question

JavaScript

Help me please.
Need to collect data into an array of clicked checkboxes, how? Here is what is ready at the moment
. It is also necessary, if the "select all" checkbox is checked and any other checkbox is unchecked (of course, the data of this checkbox is removed from the array), then the "select all" checkbox is also unchecked, but the rest remain pressed . Thank you!

I just don’t understand why the simplest operations, in one line, can be solved with the help of functions?
