How to Compare Structs in Go

Use the == operator to compare two structs of the same type for equality, which checks if all corresponding fields are equal. If the structs contain slices, maps, or functions, use reflect.DeepEqual instead.

package main

import (
	"fmt"
	"reflect"
)

type Point struct {
	X, Y int
}

func main() {
	p1 := Point{1, 2}
	p2 := Point{1, 2}
	fmt.Println(p1 == p2) // true

	s1 := []int{1, 2}
	s2 := []int{1, 2}
	fmt.Println(reflect.DeepEqual(s1, s2)) // true
}

Comparing structs in Go is like checking if two identical boxes contain the exact same items in the same order. If the boxes only hold simple items like numbers or text, you can just look at them side-by-side. If they hold complex lists or groups, you need a special tool to check every single item inside to be sure they match perfectly.
