Kujaza Arrays Multidimensional JavaScript

Hebu sasa tunataka kwa kutumia kitanzi kuunda array fulani ya multidimensional na nambari. Kwa mfano, hii array ya pande mbili:

[[1, 2, 3], [1, 2, 3], [1, 2, 3]]

Wacha tusuluhishe shida iliyowekwa, kwa kutumia vitanzi viwili vilivyowekwa ndani. Kitanzi cha nje kitaunda arrays ndogo, na kile cha ndani - kujaza arrays hizi ndogo kwa nambari:

let arr = [];

for (let i = 0; i < 3; i++) {
	arr[i] = []; // kuunda array ndogo
	
	for (let j = 0; j < 3; j++) {
		arr[i].push(j + 1); // kujaza array ndogo kwa nambari
	}
}

console.log(arr);

Unda kwa kutumia vitanzi viwili vilivyowekwa ndani array ifuatayo:

[[1, 2, 3, 4, 5], [1, 2, 3, 4, 5], [1, 2, 3, 4, 5]]

Unda kwa kutumia vitanzi viwili vilivyowekwa ndani array ifuatayo:

[
	['x', 'x', 'x', 'x'],
	['x', 'x', 'x', 'x'],
	['x', 'x', 'x', 'x']
]

Unda kwa kutumia vitanzi vitatu vilivyowekwa ndani array ifuatayo:

[
	[
		[1, 2, 3, 4, 5],
		[1, 2, 3, 4, 5],
	],
	[
		[1, 2, 3, 4, 5],
		[1, 2, 3, 4, 5],
	],
	[
		[1, 2, 3, 4, 5],
		[1, 2, 3, 4, 5],
	],
]
