JavaScript function similar to Python range()

Question

Is there a function in JavaScript similar to Python\'s range()?

I think there should be a better way than to write the following lines every time:

Answer 1

pythonic mimics the Python range behaviour best it can using JS' generators (yield), supporting both the range(stop) and range(start, stop, step) use cases. In addition, pythonic's range function returns an Iterator object similar to Python that supports map and filter, so one could do fancy one-liners like:

import {range} from 'pythonic';
// ...
const results = range(5).map(wouldBeInvokedFiveTimes);
// `results` is now an array containing elements from
// 5 calls to wouldBeInvokedFiveTimes

Install using npm:

npm install --save pythonic
