Slices are an incredibly important data structure in Go. They form the basis for how we manage and manipulate data in a flexible, performant and dynamic way. It is incredibly important for all Go programmers to learn how to uses slices.
- Slices are like dynamic arrays with special and built-in functionality.
- There is a difference between a slices length and capacity and they each service a purpose.
- Slices allow for multiple "views" of the same underlying array.
- Slices can grow through the use of the built-in function append.

Three index slicing (Go Playground)
Part A Declare a nil slice of integers. Create a loop that appends 10 values to the slice. Iterate over the slice and display each value.
Part B Declare a slice of five strings and initialize the slice with string literal values. Display all the elements. Take a slice of index one and two and display the index position and value of each element in the new slice.
