Statically typed languages check a variable's type early in the programming lifecycle and compile time, whereas dynamically typed languages can update type at runtime. The following are some of Go's tools: Gofmtautomatically formats and indents code for readability. ...
Well, this is because in Go, the embedded struct does not have an empty value. As such, to overcome this problem, we need to change the type of FruitColour from colour to *colour (pointer to a colour instance) type fruitstruct{Name string `json:"name"` ...

This is a safe way to implement enum in golang: package main import ( "fmt" ) const ( MALE = _gender(1) FEMALE = _gender(2) RED = _color("RED") GREEN = _color("GREEN") BLUE = _color("BLUE") ) type Gender interface { _isGender() Value() int } type _gender int func (...
