vals := make([]int, 5)mySlice := []int{1, 2, 3, 4, 5}Slices can be created with the built-in make function;
this is how you create dynamically-sized arrays
The make function allocates a zeroed array and returns a slice that refers to that array:
a := make([]int, 5) // len(a)=5
To specify a capacity, pass a third argument to make:
b := make([]int, 0, 5) // len(b)=0, cap(b)=5
b = b[:cap(b)] // len(b)=5, cap(b)=5
b = b[1:] // len(b)=4, cap(b)=4
