Let's look at a specific example. Assume that there is a very time-consuming wait operation: 　　Var wait = function () {var tasks = function () {alert ("execution completed!

In multi-threaded applications, we have some common requirements, such as scheduled tasks or long-time tasks, progress can be displayed during the execution of this task (you can think of a new thread to achieve this requirement to avoid blocking UI updates ). Ready-made components are provided for these applications. net. First, let's take a look at the timer component of system. Threading. It provides a method to regularly execute a task: Threadpool .
