Nodejs SQL scope

/*
I want this code to return the array of students that is generated by going through the SELECT statement.
Due to db.each going off on its own thread, the `students` array it populates is in a different scope
to the one I declare which is returned empty before the db.each finishes.

How do I get the `return` to return the data?

    searchStudents: ({term}) => {

        var lessons = ['maths', 'English'];
        var students = [];

        console.log (students);
            db.each(`SELECT * FROM students`, (err, row) => {
                if (err) {
                    console.error(err.message);
                } else {
                    student = new Student (row.id, row.name, lessons, row.password, row.attendence);
                    students.push (student);
                    console.log(row.id + "\t" + row.name + "\t" + row.password);
                }
            });
        console.log (students);

        return students;
