Course Introduction：By providing image files of different resolutions or sizes, the srcset attribute enables the browser to select the most appropriate image based on the device's screen size, pixel density and network conditions, thereby improving page loading speed and visual quality. 1. When using the width descriptor (w), images of different widths need to be listed in the srcset (such as 480w, 800w), and the display width of the image at different breakpoints should be defined with the sizes attribute, so that the browser can select the best image based on this; 2. When using the pixel density descriptor (x), corresponding images can be provided for standard screens (1x), Retina screens (2x), etc., suitable for scenes where only pixel density needs to be adapted; 3. Combining srcset and sizes can achieve fully responsive images, and self-responsive images can be achieved in different layouts.

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.
