SOLVED: Studying go, the way to simmer this down? – Getting Assist

I’m within the means of studying go. The under code is an experiment and just about self explanatory. It produces the anticipated consequence.

package deal major

import "fmt"

func major() {
	a := []int{1, 2, 3}
	z := map[string]func(x int) []int{
		"add": func(x int) (b []int) {
			b = a
			for ok, _ := vary b {
				b[k] += x
			}
			return
		},
		"sub": func(x int) (b []int) {
			b = a
			for ok, _ := vary b {
				b[k] -= x
			}
			return
		},
	}
	fmt.Println("add 3:", z["add"](3))
	fmt.Println("sub 100:", z["sub"](100))
}

I assume the b = a might be eradicated whereas conserving the identical conduct, however how?

I wish to apply my understanding of slices, maps, and nameless features, in order that’s why I took this strategy.

NOTE: I wish to iterate over the entire a slice whether or not it’s 3 gadgets or 100.

EDIT: Stack overflow to the rescue!. It mainly comes right down to the actual fact I didn’t want the reassignment in any respect and I used to be heading in the right direction with utilizing indexes. Right here’s what I ended up with:

package deal major

import "fmt"

func major() {
	a := []int{1, 2, 3}
	z := map[string]func(x int) []int{
		"add": func(x int) []int {
			for ok, _ := vary a {
				a[k] += x
			}
			return a
		},
		"sub": func(x int) []int {
			for ok, _ := vary a {
				a[k] -= x
			}
			return a
		},
	}
	fmt.Println("add 3:", z["add"](3))
	fmt.Println("sub 100:", z["sub"](100))
}
