golang javascript对象等效项

Question

In Javascript, we can create objects like this:

var car = {type:"Fiat", model:"500", color:"white"};

So if we want to print the car's model, then we do this in the console:

console.log(car.model);

or

console.log(car['model']);

Then, we will get:

"500"

Does Golang have something similar to Javascript Objects? Or how can I approach to this solution?

Answer 1

Golang is a statically typed language, so generally you would define the data type ahead of time, specifying field types and such to allow the compiler to check type mismatches for you.

Or you can use a map as long as all the values stored in there are of the same type:

package main

import "fmt"

type car struct {
    Type  string
    Model string
    Color string
}

func main() {
    c1 := car{
        Type:  "Fiat",
        Model: "500",
        Color: "white",
    }
    fmt.Println(c1.Model)

    c2 := map[string]string{
        "Type":  "Fiat",
        "Model": "500",
        "Color": "white",
    }
    fmt.Printl(c2["Model"])
}
