break continue 一些循环逻辑练习题

break continue

终止当前循环

for(var i = 1; i <= 100; i++){
   
   
	if(i == 5){
   
   
	break;
	}
	document.write("<br>");
}

去掉这次循环

for(var i = 1; i <= 100; i++){
   
   
	if(i == 5){
   
   
	continue;
	}
	document.write("<br>");
}

找质数

var num = 9;
var isYes = false;
for(var i = 2; i < num; i++){
   
   
	if(num % i == 0){
   
   
	isYes = true;
	break;
	}
}
