Encode Collections

Small slices and maps can be represented as JSON arrays and objects.

package main

import (
	"fmt"
)

func main() {
	var apples = 
	counts := map[string]int{
		"apples":  apples,
		"oranges": 2,
	}

	total := counts["apples"] + counts["oranges"]
	text := fmt.Sprintf(`{"apples":%d,"oranges":%d}`, counts["apples"], counts["oranges"])
	fmt.Println("apples=", counts["apples"])
	fmt.Println("total=", total)
	fmt.Println("json=", text)
}

package main

import (
	"fmt"
)

func main() {
	var apples = 
	counts := map[string]int{
		"apples":  apples,
		"oranges": 2,
	}

	total := counts["apples"] + counts["oranges"]
	text := fmt.Sprintf(`{"apples":%d,"oranges":%d}`, counts["apples"], counts["oranges"])
	fmt.Println("apples=", counts["apples"])
	fmt.Println("total=", total)
	fmt.Println("json=", text)
}

package main

import (
	"fmt"
)

func main() {
	var apples = 
	counts := map[string]int{
		"apples":  apples,
		"oranges": 2,
	}

	total := counts["apples"] + counts["oranges"]
	text := fmt.Sprintf(`{"apples":%d,"oranges":%d}`, counts["apples"], counts["oranges"])
	fmt.Println("apples=", counts["apples"])
	fmt.Println("total=", total)
	fmt.Println("json=", text)
}

collection encoding JSON arrays and objects map naturally to Go slices and maps when the values are small and deterministic.
