JS Array 0 à n

const range = ({
  from = 0,
  to,
  step = 1,
  length = Math.ceil((to - from) / step),
}) => {
  return Array.from({ length }, (_, i) => from + i * step);
};

console.log(
  range({length: 5}), // [0, 1, 2, 3, 4]
  range({to: 5}),    // [0, 1, 2, 3, 4]
  range({from: 2, to: 5}),    // [2, 3, 4] (inclusive `from`, exclusive `to`)
  range({from: 2, length: 4}), // [2, 3, 4, 5]
  range({from: 1, to: 5, step: 2}), // [1, 3]
  range({from: 1, to: 6, step: 2}), // [1, 3, 5]
