来，把settimeout的代码改成我们想要的结果

Question

constobj={
name:"jsCoder",
skill:["es6","react","angular"],
say:function(){
for(vari=0,len=this.skill.length;isetTimeout(function(){
console.log(i);
console.log(this.skill[i]);
}(i),0)
console.log(i);
}
}
};
obj.say();
改成settimeout中可以正常顺序打印i和依次打印skill，大家都懂的，有哪些方法，各位发挥
