Testing is a bit lacklustre

[mynlexi]

1. for arrays -> they dont go from 1 to 100, but from 0-> 99
2. filtering -> the testing-case is lazy eg. this works:
   exports.findStudentName = function findStudentName(students, name) { return students //correct: return students.filter(student => student.name === name) };
3. no test case for the Js Assignment done. #5 (y is type undefined, not type y: 2)
