Description
An empty slice can be represented by nil or an empty slice literal. They are
functionally equivalent — their len and cap are both zero — but the nil
slice is the preferred style. For more information about empty slices,
see Declaring Empty Slices.
Bad practice
package main
func foo() {
a := []int{}
}
Recommended
package main
func foo() {
var a []int
}
