Pass a slice to a variadic Go function by using the spread operator (...) to unpack its elements as individual arguments.
Use the spread operator (...) to unpack the slice into individual arguments when calling the variadic function.
values := []int{1, 2, 3}
variadicFunc(values...)
This syntax tells the compiler to pass each element of values as a separate argument to variadicFunc instead of passing the slice itself as a single argument.
A variadic function accepts a flexible number of arguments, like a list. If you already have your data in a slice (a fixed list), you cannot pass the whole list directly. Instead, you use the spread operator to "unpack" the list so the function sees each item individually, just as if you had typed them out by hand.
