There are no way to get variable value from one function to another unless you pass it by parameter or set it as global variable.

When executing loginMe(). You can pass value by calling getUserInfo( username ). Or when you are executing loginMe() you can set username in localStorage and get it in getUserInfo() function from localStorage. Or You can set the value as global variable by window.username then you will be able to access it.

where do I put the window.username at? – Vicks Feb 04 '22 at 15:35 — Vicks, Feb 04 '22 at 15:35
