Course Introduction：Advantages and Disadvantages of Go Language Functions In the Go language, functions are the basic unit of code organization and reuse. They offer some advantages, but also some disadvantages to be aware of. Advantages: Encapsulation: Functions encapsulate related code into independent units, improving the readability and maintainability of the code. Code reuse: Functions can be reused to avoid redundant code. Testability: Functions serve as independent unit tests, making it easier to write and maintain test cases. Code example: //Calculate the sum of two numbers funcsum(a,bint)int{returna+b} Disadvantages: stack space occupation: function calls will use stack space, too many or deeply nested function calls may cause stack overflow mistake. sex
