var arr1 = [
{userId: 1, name:'清北'},
{userId: 2, name:'浙京'}
]
var arr2 = [
{role: "1", group: "3"},
{role: "1", group: "2"}
]
//输出结果
console.log(arr2.map(z=>arr1.map(x=>({...x, ...z}))).flat())
//0: {userId: 1, name: '清北', role: '1', group: '3'}
//1: {userId: 2, name: '浙京', role: '1', group: '3'}
//2: {userId: 1, name: '清北', role: '1', group: '2'}
//3: {userId: 2, name: '浙京', role: '1', group: '2'}
