How to display all data from an array except data from another array in Angularjs?

Question

Angular

There is an array of students. Students are added to groups.
When adding/removing students, there are 2 tables: students in a group and a general list of students. At the moment, the general list of students is fixed.
I want to do something so that if I add student id-1 to a group, he was not displayed in the general list, because there is no point in adding it again.

Answer 1

Angular has nothing to do with it at all.
You have an array of students, each student in the data has an indicator whether the student is added to any group or not added - such as group_id: group ID or null. So filter by this parameter.
Or make two arrays, one for each table, and work with two arrays - delete / add.
