In the above statment , its alerting the argument without waiting for 5 second because , its not you can use setTimout function in that way , its because setTimeout function is not working , so only executing myalert() function without creating Delay.

Its due to the incorrect usage of settimeout function () i.e. missing quotes around argument provided..

setTimeout(myalert(‘Does not wait for five seconds’), 5000 );

function myalert(str)
{
alert(str);
}

can you please explain me the difference??
