No, Go does not natively support optional parameters in functions. However, there are several patterns and techniques that developers can use to simulate the behavior of optional parameters.
Variadic Functions: These functions accept a variable number of arguments, allowing them to be called with different numbers of parameters. This can be used to simulate optional parameters by checking the number of arguments received within the function[1][2].
Pointers: By using pointers for function parameters, you can pass a nil value to signify that no value has been provided for that parameter. This allows the function to assign a default value when nil is encountered[1][2].
Structs with Default Values: You can define a struct that includes all possible parameters and pass an instance of this struct to your function. The struct can be populated with default values, and only the values that need to be overridden can be set before calling the function[1][2].
Functional Options Pattern: This involves using functions that set configuration optio...
