Kuongeza Vipengele kwa Vitu vya JavaScript vilivyo na Vipimo Vingi

Acha tuwe na kitu kifuatacho cha wanafunzi:

javascriptlet students = {
  'group1': ['student11', 'student12', 'student13'],
  'group2': ['student21', 'student22', 'student23'],
  'group3': ['student31', 'student32'],
};

Wacha tuongeze mwanafunzi mwingine katika kikundi cha kwanza:

javascriptstudents.group1.push('student14');

Wacha sasa tufanye kikundi cha nne na tuongeze mwanafunzi ndani yake. Ili kufanya hivyo, kwanza ni lazima tutangaze kikundi kipya kuwa safu (array):

javascriptstudents.group4 = [];

Na ndipo tuweze kuongeza wanafunzi ndani yake:

javascriptstudents.group4.push('student41');
