1、break

  1. for(var i=0;i<=5;i++){
  2.             if(i == 3){
  3.                 break
  4.             }
  5.             console.log(i)
  6.         }

2、continue

  1.     //continue跳过某个条件，继续循环
  2.         for(var a=0;a<=6;a++){
  3.             if(a == 3){
  4.                 continue;
  5.             }
