关于JavaScript中函数执行顺序的问题

Question

你好朋友，我的问题是我有两个函数f1和f2，如果我想在执行f1之后执行函数f2，那怎么可能？

Answer 1

f1();
f2();

JavaScript is single-threaded, so code is executed linear-ly (is that a word?).

Answer 2

You will have to be a little bit more clear about that

You can have

function f2(){
}

function f1(){
   //do something
   f2();
}

or

function f2(){
}

function f1(){
}

function f3(){
   f1();
   f2();
}
