Two range calculating functions using idiomatic ES6

range.js

export const stepout = (min, max, step = 1) => (
  Array( Math.floor((max - min) / step) ).fill().map( ( _, i ) => min + (i * step) )
);

export const linspace = (min, max, n = 100) => {
  const step = (max - min) / (n - 1);
  return Array( n ).fill().map( ( _, i ) => min + (i * step) );
};

export default stepout;
