JS⟩ iteration ⟩ custom generators ⟩ *closeRange()
💾 replit:closed range (generator)
👉 compare: ClosedRange (the hard way), *list()
// ⭐️ (closed) range of integers
function* closedRange(start, end) {
for (let i = start; i <= end; i++) { yield i }
}
💈範例:
for (const i of closedRange(1, 3)) console.log(i); // 1 2 3
[...closedRange(-2, 2)], // [ -2, -1, 0, 1, 2 ]
