JavaScript返回函数的含义

Question

I understand return basically terminates a function. But somehow in this case, I'm not sure which return is actually finishing up a function.

var THRESHOLD = 12;
var v = [5, 2, 16, 4, 3, 18, 20];
var res;

res = v.some(function(element, index, array) {
  console.log('element:', element);
  if (element >= THRESHOLD) {
    return true; //#1
  }

  return false; // #2
});
console.log('res:', res);

Say it's iterating at v[0]=5, it skips if(){} and go ahead to return false //2 , Why is that after #2 return, the function still keep looping?

Answer 1

The function does not keep running. It is being called several times because you are iterating over the array

Answer 2

发生这种情况是因为第一个元素小于10，并且第一个返回false杀死了循环。
