in the last wordsToday's JavaScript engine has a strong ability to automatically reclaim the memory garbage generated by the code. That is, they can only do this, but our application is still proving to be a memory leak due to a logical error. Use the appropriate tools to find the application's bottleneck, and remember, don't rely on guessing – test it.Help instances diagnose memory leaksAlthough a lot of the content has been mentioned in this article, a series of examples of testing memory-rel
case of document existence.
There are many objects that may have been created when debugging code or in Devtools console (e.g., after some code execution in the console has finished).
Note: We recommend that users do not execute code in the console or enable debug breakpoints when creating a heap snapshot.The memory map starts with a root, possibly a browser window object or a node Global . JS Module object. How these objects are reclaimed by memory is not under the control of the user
This article describes my analysis of the user authentication module for the Giuhub official app. Giuhub's official app is a very small program, but from the point of view of program design, this is a very good project. For its user authentication module, I was left with a very deep impression. If you are interested in this, please go to my blog, the address is as follows:Address: http://kohoh1992.github.io/GithubAppAccountAuthenticatorAnalysis/Oh, that's right. I forgot to add that the articles

. ? classes.dex fileClasses.dex is a Java bytecode file generated after the Java source code is compiled (first, the Java file is compiled into a bytecode file via the JDK and then compiled by Dex into Classes.dex). However, because the Dalvik virtual machine used by Android is incompatible with the standard Java Virtual machine, the Dex file is different from the class file, whether it is a file structure or opcode. None of the common Java Anti-compilation tools currently work with Dex files. T
