javascript - 使用JavaScript中两个1D数组的成对元素创建2D数组

Question

const A = [1,2,3,4,5]
const B = [6,7,8,9,10]
const C = [];
for (let j=0; j<A.length;j++){
  C[j] = C[[A[j],B[j]]
}

我想创建一个2D数组C C = [[1,6],[2,7],[3,8],[4,9],[5,10]]

Answer 1

您可以使用Array.prototype.map()

码:

const A = [1,2,3,4,5]
const B = [6,7,8,9,10]
const C = A.map((item, index) => ([item, B[index]]));

console.log(C);
