golang init slice code example

Example 1: golang size of slice

// Create an exmaple array
    array := []int{1, 2, 3, 4, 5}
// Print number of items
    fmt.Println("First Length:", len(array))

Example 2: go create list length

vals := make([]int, 5)

Example 3: go slice initialization

mySlice := []int{1, 2, 3, 4, 5}

Example 4: go slice

// loop over an array/a slice
for i, e := range a {
    // i is the index, e the element
}

// if you only need e:
for _, e := range a {
    // e is the element
}

// ...and if you only need the index
for i := range a {
}

// In Go pre-1.4, you'll get a compiler error if you're not using i and e.
// Go 1.4 introduced a variable-free form, so that you can do this
for range time.Tick(time.Second) {
    // do it once a sec
}
