Simple range iterator.
range() method creates a Range object as follows:
range(1, 5); // [1, 2, 3, 4] range(1, 8, 2); // [1, 3, 5, 7]
Range class implements Iterable, so you can easily iterate over it:
range(0, 3).forEach((e) => print(e)); // 0, 1, 2
For creating detailed ranges, you have:
inclusiveRange(begin, end, [step]); // [begin, end] exclusiveRange(begin, end, [step]); // (begin, end) openClosedRange(begin, end, [step]); // (begin, end] closedOpenRange(begin, end, [step]); // [begin, end)
You can also create a infinite range:
inifiniteRange(begin, [step]); // [begin, infinity) openInfiniteRange(begin, [step]); // (begin, infinity) closedInfiniteRange(begin, [step]); // same as infiniteRange
If you need a type-specific range, please use:
range<int>(begin, end); inclusiveRange<int>(begin, end); range<double>(begin, end); inclusiveRange<double>(begin, end); // and so on
