The longstanding best practice: use i += 1 instead, following jslint’s advice.
As for why it is a better practice than ++, according to Crockford:
The increment
++and decrement--operators make it possible to write in an extremely terse style. In languages such as C, they made it possible to write one-liners that:for (p = src, q = dest; !*p; p++, q++) *q = *p;Most of the buffer overrun bugs that created terrible security vulnerabilities were due to code like this. In my own practice, I observed that when I used++and--, my code tended to be too tight, too tricky, too cryptic. So, as a matter of discipline, I don’t use them any more.
