Course Introduction：To make multiple animations play in sequence, you can set delays through CSS's animation-delay to achieve simple concatenation; use JavaScript to listen for events or setTimeout for dynamic control; or use the timeline functions of animation libraries such as GSAP to arrange animations in order. 1. The CSS method realizes sequential playback by adding a delay value equal to the duration of the previous animation to the subsequent animation, which is suitable for simple scenes; 2. The JS method triggers the next animation by listening to the animationend event or using setTimeout, which is flexible and controllable but requires compatibility; 3. Animation libraries such as GSAP provide timeline functions, which can easily manage complex animation sequences and support intervals and overlapping effects; pay attention to delay calculation

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.
