F2F: 2 - Frontend (Two interviewers) Create a function to fetch and render an array of stocks (stock_id, stock_name, price). Follow up questions: - Automatically refresh data (your solution must be "user-friendly". ex. re-render every 3 seconds) - Create an additional list of "3 Favorite stocks" and link it to the bottom of the page. (use "div", use position: fixed; bottom: 0). On this step, they asked a lot about CSS Position (absolute, fixed, etc) - What if there are 10000+ stocks? Should we render them all? Should we re-fetch them all? (Answer: re-fetch/re-render only first N of stocks + re-fetch/re-render favorite stocks)
