Can anyone please tell me why it's answer is 04

Question

for(i=0;i<=5;i++){
i += i;
console.log(i);
i++;
}

Answer 1

First iteration ( i = 0 )
i += i; // still 0
i++; // becomes 1
i++ // becomes 2 ( in loop construct )

Second iteration ( i = 2 )
i += i; // becomes 4
i++; // becomes 5
i++ // becomes 6 ( in loop construct )

Loop cease repetition cause <i> is now 6, which means the condition i <= 5 no longer satisfy.

Answer 2

console.log() prints its argument in separate line. I got the below result in JS console

0
4

Answer 3

then why my console is showing 0 4 output

Answer 4

First iteration:
i=0;
Print 0
Second interaction:
i=1
i++=2
i+=i Print 4
