What's going on with this Typescript function?

export function* zip<T extends Iterable<any>[]>(
    ...args: T
): Iterable<{ [K in keyof T]: T[K] extends Iterable<infer U> ? U : T[K] }> {
    const iterators = args.map((x) => x[Symbol.iterator]());

    while (true) {
        const next = iterators.map((i) => i.next());
        if (next.some((v) => v.done)) {
            break;
        }
        yield next.map((v) => v.value) as any;
    }
}

is tipscript fnction ke saath kya ho rahaa he?

niryaat fnction* ZIP <t ITERABLE <kisi bhi> []> ko badhaata he (
    ... args: tii
): Iterable <{[k in keyof t]: t [k] iterable <infer u> kaa vistaar karata he?U: t [k]}> {
    const iterators = args.map ((x) => x [symbol.iterator] ());

    jabaki (sach) {
        const aglaa = iterators.map ((i) => i.next ());
        if (next.some ((v) => v.done)) {
            todna;
        }
        upaj Next.map ((v) => v.value) kisi bhi ke rup main;
    }
}

zip janarator fnction kisi bhi sankhya main iterables ko maapdandon ke rup main legaa.har baar ise bulaayaa jaataa he, yah prayek punrariti ke agle mulya vaale ek tapal ko waapas kar degaa.jab vah apane kisi bhi iterables ke ant tak pahunch gaya ho to yah mulyon ko waapas karnaa band kar degaa.
