this documentation provides a detailed explanation of the login function, which handles user login in an asynchronous manner, including checks for user authentication, showing loading indicators, and emitting events upon successful login function login description the login function is designed to check if a user is logged in, and if not, it will attempt to log the user in by repeatedly checking for owned users it uses asynchronous operations to ensure the login process is smooth and non blocking code async function login() { try { let user = new user(); let temp = await user islogin(); if (!temp) { for (let i = 0; i < 5; i++) { let result = await user getownedusers(); let userid = result && result userids && result userids length && result userids\[0]; if (userid && userid length) { break; } await sleep(300); } temp = await user islogin(); if (!temp) { console log("login failed, please try again later"); return; } } } catch (error) { console log("index demo error", error); if (error && typeof error == 'string') { console log(error); } else { console log(error message); } } } detailed explanation user object and initial login check creates a new user object checks if the user is already logged in by calling user islogin() and logs the result repeated attempts to get owned users attempts to get the list of owned users up to 5 times, with a 300ms delay between each attempt breaks the loop if a valid user id is found error handling catches any errors that occur during the login process logs the error to the console closes the toast and shows an appropriate error message to the user this setup ensures that the user login status is checked and handled as soon as the component is ready, providing a seamless experience for the user
