函数参数的解构赋值

add([101, 202])
    // 函数 参数的解构赋值
    function add([x, y]) {
        console.log(`x=${x}, y=${y}`)
    }


    function move({num1 = 0, num2 = 0} = {}) {
        console.log(`num1=${num1},  num2=${num2}`)
    }
    move() // 0, 0
    move({num1: 1, num2: 2}) // 1, 2
    move({num1: 10}) // 10, 0
    move({}) //0, 0


    // 函数参数的解构赋值
    function requestNet({payload, userDto}, {port, url}) {
        console.log(payload) //{per: 10, page: 1}
        console.log('hobby = ' + userDto.hobby) // 篮球足球
        console.log('port = ' + port) // 8080
        console.log('url = ' + url) // http://www.baidu.com
    }

    const params = {payload: {per: 10, page:1}, userDto: {age: 18, hobby: '篮球足球'}};
    const call = {port: 8080, url: 'http://www.baidu.com'}
    requestNet(params, call)
