Where to Learn Golang Programming Language in 2023

There are a few reasons why Golang has become popular in recent years. First, it was developed by Google, which means it has the backing of a major tech giant. Second, it’s a compiled language, which means it’s generally faster than interpreted languages like Python. Third, it has a very clean and concise syntax, which makes it easy to learn and read. Finally, it has built-in support for concurrency, which makes it ideal for developing scalable web applications.

What are the best places to learn Golang?

Golang, also known as Go, is a programming language designed at Google by Robert Griesemer, Rob Pike, and Ken Thompson. It was open sourced in 2009. Go is a statically typed, compiled language with garbage collection, memory safety, and CSP-style concurrent programming features.

The syntax of Go is inspired by the C family of languages but is significantly different. One of the major differences is that Go does not have classes or inheritance. Instead, it uses composition and embedding to provide code reuse.

One of the design goals of Go is to make it easy to build simple, reliable, and efficient software. Go is often used for system programming, network programming, web development, and package management.

There are a few different ways to learn Golang. One way is to find a tutorial or article online and follow along. This can be a good option if you want to learn at your own pace and don’t need much structure.

Another way to learn Golang is to join a community or online course. This can be a good option if you want more support and guidance from other people who are learning the language.

If you want to learn Golang in-person, you can find a Golang meetup in your area or join a Golang programming club at your university.

There are also a number of bootcamps that teach Golang. This can be a good option if you want a more immersive learning experience.

No matter how you choose to learn Golang, the important thing is to start learning and practicing. The more you use the language, the better you will become at using it.

How to read JSON file in Golang?

In order to read JSON in go file in Golang, you first need to open the file using the os. Open() function. This function will take the path to the file as an argument and return a file pointer.

Once the file is open, you can use JSON.NewDecoder() function to create a JSON decoder. This decoder can then be used to decode the JSON data into a Go data structure.

In order to decode the data, you will need to know the type of data structure into which the data will be decoded. For this example, we will use a map[string]interface{} . This type of data structure is a map that can hold any type of data.

Once you have created the decoder, you can use the decoder.Decode() function to decode the data. This function will take an interface{} as an argument and will fill the interface with the decoded data.

Finally, you can print out the data to see what was decoded.

This example will decode a JSON file that contains a list of names and ages.

package main

import (





type Person struct {

Name string

Age  int


func main() {

// Open the file.

f, err := os.Open(“people.json”)

if err != nil {




defer f.Close()

// Create a decoder.

dec := json.NewDecoder(f)

// Decode the file into a slice of Person objects.

var people []Person

err = dec.Decode(&people)

if err != nil {




// Print the people.

for _, p := range people {

fmt.Println(p.Name, p.Age)



What career opportunities are there for people who know Golang?

There are many career opportunities for people who know Golang. Some of these include working as a software engineer, a web developer, or a system administrator. Golang is a powerful programming language that is becoming increasingly popular in the tech industry. It is a great language to learn if you are looking to start or further your career in the tech industry.
