JavaScript深度嵌套数组过滤

您需要filter通过includes对colour阵列的测试：

const myCars = [
    { name: "BMW",colour: ["White","Red","Black"] },
    { name: "AUDI",colour: ["Yellow","Silver"] },
    { name: "VW",colour: ["Purple","Gold"] },
    { name: "NISSAN",colour: ["White","Black"] },
    { name: "SUZUKI",colour: ["Red"] }, 
];
const show1 = document.getElementById("show1");
myCars
  .filter(({ colour }) => colour.includes('Red'))
  .forEach(({ name, colour }) => {
    show1.innerHTML += name + " " + "has these colours - " + colour + "
";
  });
