Sequence.prototype.@@iterator() as Object
Summary
Return an iterator object. A Sequence is flattened when iterated through. Advancing the returned iterator does not side-effect the Sequence.
Example
const docs = fn.doc(); const i = 0; for (const doc of docs) i++; for (const doc of docs) i++; i; // Returns 2 * the number of documents
Example
const s = Sequence.from("javascript", x=>x.toUpperCase());
const it = s[Symbol.iterator]();
[s, it.next().value];
// Returns: [["J", "A", "V", "A", "S", "C", "R", "I", "P", "T"], "J"]
