The Command Editor evaluates the code entered and outputs its result. So
the last number listed in the output (1346269) is the value returned by
your code.
So if you execute 1+1 into the Command Editor or Command Line, you'll get 2
as result.
You can verify that by logging your numbers using some styling:
var x1=0;
var x2=1;
var x3;
console.log(x1);
while(x2<1000000){
console.log('%c' + x2, 'color: green;');
x3=x1;
x1=x2;
x2=x3+x2;
}
By that the output of your code will be listed in green while the return
value of the evaluation will still be shown in dark blue.
To avoid getting the last number simply put your calculation code into a
function and call that function:
function fibonacci(x1, x2) {
var x3;
console.log(x1);
while(x2<1000000){
console.log(x2);
x3=x1;
x1=x2;
x2=x3+x2;
}
}
fibonacci(0, 1);
Then the last logged line will be undefined indicating that the evaluated
code didn't return anything.
