Hands-On Full Stack Development with Go

GopherJS types

GopherJS includes a sub-package called js. This package provides the functionalities needed to bridge between Go and JavaScript. The package can be found at https://godoc.org/github.com/gopherjs/gopherjs/js.

The key feature provided by the js package is the ability to transform Go types into JavaScript types, and vice versa. 

When we consider data types, there are two main categories that need to be supported: basic types (int, float, and string) and constructed types (structs and interfaces). The following table shows the type mappings between Go basic types and JavaScript types, as supported by GopherJS:

Go type	JavaScript type
bool	Boolean
int and float	Number
string	String
[]int8	Int8Array
[]int16	Int16Array ...
