Learning a new language is nothing more than starting with the basic grammar. It is boring to learn a language through grammar books, so we may as well start learning a new language from the simplest examples. There are few examples, but they are representative.

(a) The simplest code

Package Mainimport "FMT" Func Main () {        fmt. Println ("Hello, World")}

    (b) Basic functions

Package Mainimport "FMT" func sub (a int, b int) int {        return a-B;} Func Main () {        fmt. Println (Sub (2, 3))}

    (c) If statement learning

Package Mainimport "FMT" func compare (a int, b int) {        if (a > B) {                FMT. Println ("Greater")        }else{                FMT. Println ("smaller")        }}func Main () {        compare (3, 2)}

(d) switch statement learning

Package Mainimport "FMT" func Test (a int.) {        switch (a) {case                1:                        FMT. Println ("1") Case                2:                        FMT. Println ("2")                default:                        FMT. PRINTLN ("error")        }}func Main () {        Test (1)        Test (2)        Test (3)}

    (e) cyclic sentence learning

Package Mainimport "FMT" func Show (data int) {        var index int        index = 0 for        {                if (index >= data) {                        bre AK                }                FMT. PRINTLN (Index)                index + +                continue        }}func Main () {        Show (10)}

(f) Structural learning

Package Mainimport "FMT" type node struct {        data Int}func (p* node) set (val int) () {        p.data = Val}func (p* node) get () int {        return p.data;} Func Main () {        N: = node{data:10}        m: = &n        m.set ()        FMT. Println (M.get ())}

Say so much first, next time to introduce a bit more advanced features.
