The examples in this article illustrate the usefulness of JavaScript to avoid memory leaks and memory management techniques. Share for everyone to use for reference. The specific methods are as follows: This article originates from Google Webperf (London webperf Group), August 26, 2014. In general, efficient JavaScript Web applications must be fluent and fast.

Memory leaks before, because in a few G memory of the computer, forgot to delete an object, how much memory ah?The result of this problem, my program all night operation, every 10 times after the task, the program will crash, starting from the print log, I think it is not properly loaded pictures, and also suspect that

A regular local update was used for the page when it was recently developed, results in ie6,7 and Firefox, all normal, and in the IE8 after a few hours on the browser crashed, showing the memory overflow, I thought it was bad code write to lead to memory leaks, but ie6,7 and normal, investigated a bit, It turned out to be a IE8 bug. Problem points In IE8, the

Reason: Modify the previous code: W.insert (user); W.fireallrules (); W.dispose (); after the modified code: facthandle fact = w.insert (user); W.fireallrules (); W.dispose (); W.retract (fact); or: W.insert

program's UI views and resources. Suppose we have a program that uses a large bitmap image, and we don't want to reload the bitmap object each time the screen rotates, the easiest way is to use the static modifier for the bitmap object. private static drawable Sbackground; @Override protected void onCreate (Bundle state) { super.oncreate (state); TextView label = new TextView (this); Label.settext ("Leaks are bad"); if (Sbackground = =

Consequences:A small memory leak that occurs only once may not be noticed, but a program that leaks large amounts of memory or leaks a growing number of programs may exhibit a variety of symptoms: from poor performance (and gradual degradation) to full memory exhaustion.Wor

The memory of the mobile device is a shared resource. Applications may run out of memory, crash, or experience significant performance degradation.The Facebook iOS client has many features, and they share the same block of memory space. If any particular feature consumes too much memory, it affects the entire applicati

Java Memory Management mechanismIn the C + + language, if you need to allocate a chunk of memory dynamically, programmers need to be responsible for the entire life cycle of this memory. From the application assignment, to the use, to the final release. The process is very flexible, but cumbersome, and the programmer is prone to inadvertently forget to release

Although in Java we do not care about the release of memory, the garbage collection mechanism helps us to reclaim unwanted objects, but in fact improper operations can also produce memory problems: memory overflow, memory leaksMemory overflow: Out of memory: a simple, easy-t

After the process finishes, all memory for the process is freed, including memory leaks on the heap. The reason is that when the process is finished, the GDT, LDT, and page directories are changed by the operating system, the logical memory is all gone, the contents of the physical
