Other ways to increment a variable in JavaScript [duplicate]

Answer 1

I think this is rather controversial, and I personally stick to i++ in loops. Of cource, you can replace it with i = i + 1 in your loop statement, to be fully compliant to JSLint.

There aren't real alternatives to increment and decrement numerical values in JavaScript. You can often use Array.forEach() and/or Object.keys() in order to prevent numerical indexes.
