Java script while loop stange behaviour in chrome console

Why does this:

i=0;
while(i<=4){
    console.log(i);
    i = i+1;
}

outputs: 0,1,2,3,4,5 but it should stop on the 5-th( 0,1,2,3,4 ) element not 6th(5)

PS: this happens if you paste the above code in google chrome console

This is the normal behavior under Chrome. It displays the last line evaluated. For instance, if you just enter: i=5; it will display 5 even though you didn't ask to display it through console.log. In your example the last line evaluated is i=i+1; which, at this point, computes the 5 value.

The 5 isn't in logged in the loop, but its the i variable.

i=0;
while(i<=4){
    console.log("log: " + i);
    i = i+1;
}
