HTML DOM (Document Object model)When a Web page is loaded, the browser creates a Document object model for the page.The HTML DOM model is constructed as a tree of objects. Windows Object Operations window.open ()-Open a new window Window.close ()-Close the current window 1.windows.open ("Part I", "second part", "Part Three", "Part IV")The first part: Write page address URLThe second part:

false, otherwise there will be no result. These two methods are used for timing, which calculates the exact time spent on an operation.Console.time ()Console.timeend ()The time method indicates that the timing begins, and the Timeend method indicates that the timing is complete. Their arguments are the names of the timers. After calling the Timeend method, the console window displays the timer name: the cost ofTime ".Console.profile ()//used to create a new performance tester (profile) whose pa
