Answer 1

constobj={
name:"jsCoder",
skill:["es6","react","angular"],
say:function(){
this.skill.forEach(function(item,index){
setTimeout(function(){
console.log(index)
console.log(item);
},0)
})
},
say2:function(){
for(vari=0,len=this.skill.length;isetTimeout(function(i,item){
console.log(i);
console.log(item);
},0,i,this.skill[i]);
}
},
say3:function(){
constarr=this.skill.slice();
leti=0;
functionpop(){
constitem=arr.shift();
if(item){
console.log(i);
console.log(item);
i++;
setTimeout(pop,0);
}
}
setTimeout(pop,0);
}
};
obj.say();
setTimeout(function(){
obj.say2();
},1000)
setTimeout(function(){
obj.say3();
},2000)

say:function()
{
varthat=this;
for(vari=0,len=this.skill.length;i{

console.log(that.skill[i]);
}(i),0)
console.log(i);
}
}
