The code itself is provided in the photos:

Answer 1

Cookies, session, localstorage.

Answer 2

This is how you write data:

localStorage.testovik = 'Здесь данные, которые ты хочешь сохранить...';

Where testovik is the key you will later access, it can be almost anything.
And then you extract it on another page:

infa = localStorage.testovik;
console.log(infa); // Выводим в консоли

I just warn you that only strings can be stored this way, that is, only text.
Objects and arrays must first be converted to text before being pushed into localStorage .
