分形數組語法

Question

我有每個陣列這樣內具有4個值和6點的陣列的陣列 -

[0,0,0,0，[] []，[]，[]，[] []]

。在每個這些陣列的餘放在這個對象創建此的副本 -

[0,0,0,0，[0,0,0,0，[] []，[]，[]，[]，[]]]，[[0,0,0,0，[] []，[]，[]，[]，[]]]，[[0 ，0,0,0，[] []，[]，[]，[]，[]]]，[[0,0,0,0，[] []，[]，[]，[ ]，[]]]，[[0,0,0,0，[] []，[]，[]，[]，[]]]，[[0,0,0,0，[] []，[]，[]，[]，[]]]]

我比重複的過程，爲每個數組。

而且再次。因此總共1 [i] +6 [i] [i] +36 [i] [i] [i] +216 [i] [i] [i] +1296 [i] [i] [i] [i] [i] [012]我] [我]

我的陣列正在做我想要的東西，是的，它工作正常，沒有性能或任何問題！ 但是!!!它看起來像這樣 -

var Pl = [0,0,0,0,[0,0,0,0,[0,0,0,0,[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]],[0,0,0,0,[],[],[],[],[],[]]],

我能做到這一點配發小？和維護存儲每個陣列（其中所有1500）上的「對象的值」的能力。使用腳本縮小效率會降低效率嗎？

謝謝！

Answer 1

你可以像這樣做一個遞歸函數。

function createArrayWithDepth(depth) { 
 
    if(depth == 0) 
 
    return []; 
 
    else { 
 
    var subArray = createArrayWithDepth(depth - 1); 
 
    return [0, 0, 0, 0, subArray, subArray, subArray, subArray, subArray, subArray]; 
 
    } 
 
} 
 

 
var array = createArrayWithDepth(3); 
 

 
console.log(array);

Answer 2

構建分形陣列的遞歸

// pattern 
 
var p = [0, 0, 0, 0, [], [], [], [], [], [] ]; 
 

 
var res = (function fractal(a, depth) { 
 
    return depth == 0 ? a: a.map(e => Array.isArray(e) ? fractal(p, depth-1) : e); 
 
})(p, 2); 
 

 

 
document.write(JSON.stringify(res, 0, 2));
