Could you help me come up with a descriptive comment for each line of this Typescript function?
export const pickKeys = <T, K extends keyof T = keyof T>(obj: T, ...keys: K[]): Pick<T, K> => {
	return keys.reduce((acc, key) => {
		if (hasKey(obj, key)) {
			acc[key] = obj[key];
		}
		return acc;
	}, {} as Pick<T, K>);
};

kya aap mujhe is tipscript fnction kii prayek pankti ke liye ek varnanaatmak tippanee ke saath aane main madad kar sakate hai?
export const pickkez = <t, k keyof t = keyof t> (obj: t, ... keys: k []) kaa vistaar karata he: pick <t, k> => {{
vaapasi keys.reduce ((acc, kunjee) => {
if (haskey (obj, kunjee)) {
acc [kunjee] = obj [kunjee];
}
asisi ritern;
}, {} as pick <t, k>);
};

yahaan prayek pankti ke upar ek varnanaatmak tippanee ke saath tipscript pikki fnction he:

export const pickkez = <t, k keyof t = keyof t> (obj: t, ... keys: k []) kaa vistaar karata he: pick <t, k> => {{
    // prayek kunjee par masping se utpaadit object lautaata he.
        vaapasi keys.reduce ((acc, kunjee) => {
        // check karata he ki kya vartmaan kunjee object main maujuud he.
                if (haskey (obj, kunjee)) {
             // yadi yah maujuud he, to object main iske mulya ke liye sanchayak main us kunjee ko set karata he.
                        acc [kunjee] = obj [kunjee];
                }
