将一个数组集成到另一个数组上的规范方法是什么

let newArray = array1.concat(array2, array3, ..., arrayN);

let array1 = [1, 2, 3];
let array2 = [4, 5, 6];

let newArray = array1.concat(array2);

console.log(newArray); // 输出: [1, 2, 3, 4, 5, 6]
console.log(array1);   // 输出: [1, 2, 3]
console.log(array2);   // 输出: [4, 5, 6]

let newArray = [...array1, ...array2, ..., ...arrayN];

let array1 = [1, 2, 3];
let array2 = [4, 5, 6];

let newArray = [...array1, ...array2];

console.log(newArray); // 输出: [1, 2, 3, 4, 5, 6]
console.log(array1);   // 输出: [1, 2, 3]
console.log(array2);   // 输出: [4, 5, 6]

let array1 = [1, 2, 3];
let array2 = [3, 4, 5];

let newArray = [...new Set([...array1, ...array2])];

console.log(newArray); // 输出: [1, 2, 3, 4, 5]

let array1 = [3, 1, 2];
let array2 = [6, 4, 5];

let newArray = [...array1, ...array2].sort((a, b) => a - b);

console.log(newArray); // 输出: [1, 2, 3, 4, 5, 6]
