New improvements in the following project (with example):

• Ok. I must use the backtick (`) for string creation, rather than concatenation (+).
• Ok. I must use vector.forEach() in place of for where necessary.
• Ok. I must use vector.splice(i,1) in place of for where necessary.
• Ok. Before performing a pop() or splice() from an array of objects, I must deallocate the object with object={} .
• Ok. I must deallocate an array with array=[], instead of for and pop().
• Ok. I must make private the methods that don't check the correctness of the input parameters or that can generate errors if used from outside.
• Ok. I must add get_stud_total(), set_stud() and get_stud() methods.
• Ok. add_student() must return the same course as the previously selected user.
