Resetting generator object in Python
...
The downside of option 1 is that it computes the values again. If that's CPU-intensive you end up calculating twice. On the other hand, the downside of 2 is the storage. The entire list of values will be stored on memory. If there are too many values, that can be unpractical.
So you have the clas...
Changing the interval of SetInterval while it's running

What's the best way to convert a number to a string in JavaScript? [closed]
...ware of the coercion rules. Ultimately developer time is more costly than CPU time, so I'd optimize for the former at the cost of the latter. That being said, in this case the difference is likely negligible, but if not I'm sure there are some decent JavaScript compressors that will optimize this ...
