Question about for loops

Why does the following code log numbers from 0 to 9 instead of 1 to 9?

is assigned as zero in the first expression, then it checks whether

is less than

and moves to the next expression which is

i++

i++

, so it should increment the value of

instead and log it

for (let i = 0; i < 10; i++) {
    console.log(i);
}

for (let i = 0; i < 10; i++) {
    console.log(i);
}
