To integrate the jQuery plug-in into an Ember application, first install jQuery using the npm package manager, and then import the plug-in into the relevant Ember components. The initialization of the jQuery plugin in the Ember component should be done within a special function named didInsertElement, using this.$ instead of $ to ensure that the plugin is initialized only for this component and does not interfere with it.

Course Introduction：To solve the problem of slowing down Chrome due to extensions or troubleshooting whether web page problems are caused by plug-ins, you can achieve it in the following three ways: 1. Use "no extension mode" to start Chrome, add code --disable-extensions to the shortcut target bar, which is suitable for temporary testing; 2. Use incognito mode to create a new incognito window, and not load most extensions by default, which is convenient for quick checking of problems; 3. Disable some extensions separately, turn off the suspicious extension switch on the chrome://extensions/ page or troubleshoot plug-ins that affect web page behavior one by one through developer mode, which is suitable for targeted debugging.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
