javascript - 如何在此 while 循环中添加计数器

Question

我需要在我的 while 循环中添加一个计数器，这样我就可以知道循环迭代了多少次。

var popSize = 100;
var endSize = 200;

var x = popSize / 3;     
var y = popSize / 4;     

while (popSize < endSize) 
{
    popSize = popSize + x - y; 
    popSize++;        
}
console.log(popSize);

Answer 1

var counter = 0;

while (popSize < endSize) 
{
    popSize = popSize + x - y; 
    popSize++;        
    counter++;
}

console.log(counter);
