A simple range iterator implementation. Supports incrementing, decrementing, and infinite ranges.

Examples

• Simple range

  for (let hour of range(24)) console.log(`${hour}:00`);

• Create a list

  const hours = [...range(24)];

• Specify start and end

  for (let hour of range(9, 17)) console.log("working");

• Infinite range (you can pass Infinity to the same effect)

  for (let value of range(10, null)) {
    const result = doSomethingWith(value);
    if (condition(result)) break;
  }

• Backwards range

  for (let value of range(20, 10)) console.log("counting backwards: " + value);

• Backwards infinite range

  for (let value of range(10, -Infinity)) {
    const result = doSomethingWith(value);
    if (condition(result)) break;
  }
