I'm just going through freedcodecamp and I'm doing the "Iterate Odd Numbers With a For Loop" section. I just have a question with regards to some unintended effects I encountered.

const myArray = [];

for (let i = 1; i < 10; i += 2) {
    myArray.push(i);
}

This is the correct answer and I got there no problem, however I'm wondering why changing the i += 2 to i + 2 generates an infinite loop?
