//...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 + "
" + pn2;

• index.html
