Some experiences and suggestions about getting started with golang

With the rapid development of the computer industry, programming languages ​​are becoming more and more diverse. Among them, Go language, as a new programming language, has attracted more and more attention from programmers. So, for beginners, how long does it take to get started with golang? This article will combine my personal learning experience to share some experiences and suggestions about getting started with golang.

1. What is golang?

Go language, also called golang, is a programming language developed by Google. It first appeared in 2009 to allow programmers to develop software faster and more securely. The design concept of Go language is famous for its simplicity, efficiency, concurrency and safety. It supports multiple programming paradigms such as object-oriented and functional programming, and has the characteristics of automatic garbage collection.

2. Basic knowledge of getting started with golang

Before learning any programming language, we first need to understand the basic knowledge of this language. The following are some basic knowledge of golang:

1. Variable declaration

In golang, you can use the var keyword to declare variables. For example:

var x int
x = 1

2. The definition and call of functions

The definition and call of functions in golang are similar to those in other languages, for example:

func add(a int, b int) int {
    return a + b
}

result := add(1, 2)

3. if statements and for loops

The use of if statements and for loops in golang is also similar to other languages, for example:

if x > 0 {
    fmt.Println("x is positive.")
} else if x == 0 {
    fmt.Println("x is zero.")
} else {
    fmt.Println("x is negative.")
}

for i := 0; i < 10; i++ {
    fmt.Println(i)
}

4. Arrays and slices

In golang, you can use arrays and slices to store a set of data. For example:

var arr [3]int
arr[0] = 1
arr[1] = 2
arr[2] = 3

slice := []int{1, 2, 3}

5. Structures and pointers

Golang can use structures to customize data types, and pointer types are also supported. For example:

type Person struct {
    Name string
    Age int
}

func main() {
    p := Person{Name: "Tom", Age: 18}
    pAge := &p.Age
}

3. Learning suggestions for getting started with golang

1. Learn the basic knowledge of golang

Before learning any programming language, you must first master it The basic knowledge is the same as learning golang well. You need to understand Golang's syntax, data types, functions, structures, pointers, concurrency and other concepts.

2. Deliberate practice

In the process of learning golang, you must not only read books, watch videos, blogs and other learning materials, but also practice deliberately, including writing some simple program and debug it. After all, theory and practice complement each other.

3. Read the source code of golang project

By reading the source code of golang open source project, you can have a deeper understanding of the practical application of golang programming and help improve your own programming. Skills and levels.

4. Participate in golang technology community activities

By participating in golang technology community activities, you can make more like-minded friends and share your programming experience and learning experience. Make progress together.

4. How long does it take to get started with golang?

Different people will have different answers when it comes to getting started with golang. If you already have a foundation in other programming languages, it will be easier to learn golang, which will take about 2 months; if you are a novice with no programming experience at all, it will take more time, and it will take about 3-4 months. time.

Of course, learning golang requires continuous practice and learning, not only to master basic knowledge, but also to continuously improve yourself in practical applications. Only by persevering and learning steadily can you explore a broader world in the world of golang programming.

To sum up, there is no fixed time for getting started with golang. It mainly depends on your personal situation and learning results. Through continuous learning and practice, I believe anyone can become an excellent golang programmer.
