Returns true if the value is empty (zero value) for comparable types. This works with strings, numbers, slices, maps, pointers, etc.

go
result := lo.IsEmpty("")
// true (empty string)

result = lo.IsEmpty("hello")
// false

result = lo.IsEmpty(0)
// true (zero value for int)

result = lo.IsEmpty(42)
// false

result = lo.IsEmpty([]int{})
// true (empty slice)

result = lo.IsEmpty([]int{1, 2, 3})
// false

result = lo.IsEmpty(map[string]int{})
// true (empty map)

var ptr *int
result = lo.IsEmpty(ptr)
// true (nil pointer)
