Which domestic companies are using Golang for development?

In today's fast-paced technological development era, more and more domestic companies choose to use Golang for development to meet the growing demand for Internet and software applications. Golang is a powerful programming language with efficient concurrency performance and concise syntax, so it is favored by many developers.

The following are some cases of domestic companies using Golang for development, as well as specific code examples:

1. ByteDance (TikTok)
   ByteDance is a well-known An Internet technology company that owns TikTok, the world's most popular short video application. The company uses Golang for large-scale concurrent processing and high-performance requirements. The following is a simple sample code for implementing a simple HTTP server:

package main

import (
    "net/http"
    "fmt"
)

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello, TikTok!")
    })

    http.ListenAndServe(":8080", nil)
}

2. Didi Chuxing
   Didi Chuxing is China's largest travel service provider and is also using Golang for development on a large scale to cope with high-concurrency order processing and vehicle dispatching. The following is a simple code example for implementing a simple public transportation travel service:

package main

import (
    "fmt"
)

typeRide struct {
    StartLocation string
    EndLocation string
}

func (r *Ride) BookRide() {
    fmt.Printf("Ride booked from %s to %s
", r.StartLocation, r.EndLocation)
}

func main() {
    ride := Ride{StartLocation: "Beijing", EndLocation: "Shanghai"}
    ride.BookRide()
}

3. Meituan-Dianping
   Meituan-Dianping is China’s leading lifestyle service platform and is also using Golang for development to support its rapidly growing business needs. The following is a simple code example for implementing a simple takeout order processing system:

package main

import (
    "fmt"
)

type Order struct {
    Item string
    Quantity int
}

func (o *Order) ProcessOrder() {
    fmt.Printf("Order processed: %dx %s
", o.Quantity, o.Item)
}

func main() {
    order := Order{Item: "Pizza", Quantity: 2}
    order.ProcessOrder()
}

The above are cases of some well-known domestic companies using Golang for development and corresponding code examples. By using Golang, these companies have improved system performance and development efficiency, and provided users with better products and services. Golang's simplicity and efficient performance have made it widely used and recognized in the Internet industry.
