Why answer 0 ,why not 4.

Question

var x = [9,5,4];
for( var i=1; i < 3 ; i++){
x[0]%=x[i];
}
console.log(x[0]);

Answer 1

At i = 1,
9 %= 5
so x[0] becomes 4

At i = 2,
4 %= 4
so x[0] becomes 0

To understand these quiz, you can add console.log to the code block to check the state changes in each iteration, like this :
