#17 JS: loop - Part 2

To fully understand how loop works, I try to break down the loop and practice like below.

1+2+........+50 Arithmetic Operations

var sum=0;
var n=1;
while(n<=200){
    sum=sum+n; → sum+=n
    n++;
}
alert(sum);

continue: command and execution

var x=0;
for(var i=0;i<200;i++){
    if(i%4==0){ → i can be divided exactly by 4.
        continue;
    }
    x++;
}
alert(x);
