For instance, we write
for (let i = 0; i < myVar.length; i += 3) {
//...
}
to increment i by 3 with i += 3.
Or we write
for (let i = myVar.length - 1; i >= 0; i -= 3) {
//...
}
to decrement i by 3 with i -= 3.
Conclusion
To increment or decrement for loop by more than one with JavaScript, we can increment with += or decrement with -=.
