javascript - 在多维数组中比较以找到在其他多维数组中使用的适当索引失败

Question

我对 Javascript 中的函数有疑问:

我只是将一个输入数组与另一个数组进行比较，并根据结果返回一些内容，但出于某种原因，我的比较不起作用...

这是我的函数:

const createArrayColor = (labels) => {
  const combi = [
    ["bronze","gold","new","silver"],
    ["bronze","gold","silver"],
    ["gold","new","silver"],
    ["bronze","gold","new"],
    ["bronze","new","silver"],
    ["gold","silver"],
    ["bronze","gold"],
    ["gold","new"],
    ["bronze","silver"],
    ["new","silver"],
    ["bronze","new"],
    ["gold"],
    ["silver"],
    ["bronze"],
    ["new"],
  ];

  const color = [
    ["#614E1A","#c49c48", "#f4f3f3", "#A5A49B"],
    ["#614E1A", "#c49c48", "#A5A49B"],
    ["#c49c48", "#f4f3f3", "#A5A49B"],
    ["#614E1A", "#c49c48", "#f4f3f3"],
    ["#614E1A", "#f4f3f3", "#A5A49B"],
    ["#c49c48", "#A5A49B"],
    ["#614E1A", "#c49c48"],
    ["#c49c48", "#f4f3f3"],
    ["#614E1A", "#A5A49B"],
    ["#f4f3f3", "#A5A49B"],
    ["#614E1A", "#f4f3f3"],
    ["#c49c48"],
    ["#A5A49B"],
    ["#614E1A"],
    ["#f4f3f3"],
  ];

  let i = 0;

  combi.forEach((c) => {
      console.log("Color: " + color[i]);
      console.log("Combi:  " + c + " ,type:  " + c.constructor.name );
      console.log("labels: " + labels + " ,type:  " + labels.constructor.name );
      console.log("Is it equal? " + (labels === c));

    if (labels === c) {
      return color[i];
    }
    i = i + 1;
  })
}

(顺便说一句，如果你知道如何在 JS 中组合数组，我也想知道，我确信有比我所做的更好的方法，但我没有找到)

正如你所看到的，我将 labels 与 combi 的每个元素进行了比较，但它始终为 false...

我认为这是我在某个地方犯的一个小错误，但我找不到它...

“c”和“labels”是两个不同的数组，内容完全相同。请参阅此 question 以了解如何比较数组。
