javascript - 如何在不硬编码的情况下解决数组问题？

Question

你如何生产这些元素？

let obs = [
    { car: cars[0], color: colors[0] },
    { car: cars[1], color: colors[1] },
    { car: cars[2], color: colors[2] }
]

来自这些无需硬编码的数组

let cars = ["audi", "audi", "audi"]
let colors = ["darkgrey", "red", "silver"]

Answer 1

使用Array.map()生成对象数组:

const cars = ["audi", "audi", "audi"]
const colors = ["darkgrey", "red", "silver"]

const result = cars.map((car, i) => ({
  car,
  color: colors[i]
}));

console.log(result);
