iterate over slice golang code example

Example 1: golang iterate through slice

var slice = []string{"Apple", "Orange", "Kiwi"}
for index, sliceItem := range slice { // You can omit index or sliceItem with a _
  fmt.Println("Index in slice:", index)
  fmt.Println("Fruit:", sliceItem)
}

Example 2: go iterate over slice

nums := []int{2, 3, 4}
    sum := 0
    for _, num := range nums {
        sum += num
    }
    fmt.Println("sum:", sum)

Example 3: range in go

kvs := map[string]string{"a": "apple", "b": "banana"}
    for k, v := range kvs {
        fmt.Printf("%s -> %s\n", k, v)
    }

Example 4: iterate over struct slice golang

for i, x := range p.Fruits
