Course Introduction：Pure functions are concepts in functional programming. They can be implemented in PHP by following specific rules. The core features include: 1. No side effects, no modification of global variables, object states or performing I/O operations; 2. The same input always returns the same output, and does not rely on external data such as time and random numbers; 3. Keep simple and focused, only process inputs and return results, and do not use reference modifications or static variables to retain state. For example, sum(int$a,int$b):int is a typical pure function that only depends on parameters and has no external influence.

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.
