javascript - Request for the username and password again if either is wrong -


how make when password and/or username wrong ask password and/or username again?

var user = prompt("please enter username continue.").touppercase();  if (user === "ryebread4") {     var pass = prompt("please enter password continue").touppercase();     if (pass === "7277") {         console.log("welcome ryebread4");     } else {         console.log("username or password incorrect! please try again");     } }

use while loop

var signedin = false; while(!signedin) { ...     if (password === "7477")     {         console.log("welcome back!");         signedin = true;      } ... }

or for (not recommend)

 var username = "";  var password = "";  for(;username !== "ryebread4" && password !== "7477";) {      //prompt user username/password       ... }

that same methodology can applied while loop, , eliminate variable.
