//...restOfname:string[] 这个写法就是可变参数的写法
function peopleName(firstName:string,...restOfname:string[]){
return firstName + " " + restOfname.join(" ");
}
let pn1 = peopleName('xiaochuan','xiaoming','xiaohong');//编译成功
let pn2 = peopleName('xiaochuan','xiaoming','xiaohong','xiaoxin');//编译成功
document.getElementById('pid').innerHTML = pn1 + "<br/>" + pn2;
