Kuongeza Vipengele kwa Vitu vya JavaScript vilivyo na Vipimo Vingi

Acha tuwe na kitu kifuatacho cha wanafunzi:

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

Wacha tuongeze mwanafunzi mwingine katika kikundi cha kwanza:

students.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):

students.group4 = [];

Na ndipo tuweze kuongeza wanafunzi ndani yake:

students.group4.push('student41');

Iakiri muundo ufuatao kuhifadhi orodha ya mambo ya kufanya kwa tarehe fulani:

let affairs = {
	'2019-12-28': ['data11', 'data12', 'data13'],
	'2019-12-29': ['data21', 'data22', 'data23'],
	'2019-12-30': ['data31', 'data32', 'data33'],
}

Ongeza jambo lingine katika tarehe '2019-12-29'.

Ongeza mambo mawili zaidi katika tarehe '2019-12-31'.

Iakiri muundo ufuatao kuhifadhi orodha ya wanafunzi:

let students = {
	'group1': {
		'subgroup11': ['student111', 'student112', 'student113'],
		'subgroup12': ['student121', 'student122', 'student123'],
	},
	'group2': {
		'subgroup21': ['student211', 'student212', 'student213'],
		'subgroup22': ['student221', 'student222', 'student223'],
	},
	'group3': {
		'subgroup31': ['student311', 'student312', 'student313'],
		'subgroup32': ['student321', 'student322', 'student323'],
	},
};

Ongeza mwanafunzi mpya katika kikundi kidogo 'subgroup11'.

Ongeza kikundi kidogo kingine katika kikundi cha kwanza.

Fanya kikundi cha nne, unda kikundi kidogo ndani yake na uongeze wanafunzi wawili wapya.
