Join David Gassner for an in-depth discussion in this video Storing ordered values in slices, part of Learning Go.
- A slice in Go is an abstraction layer…that sits on top of an array.…When you declare a slice, the run time…creates the underlying array for you,…allocates the required memory,…and then returns the requested slice.…Like arrays, all items in a slice have to be…of the same type, but unlike arrays, they're resizable,…and they can be sorted quite easily.…To declare a slice, I'll start with the var keyword,…and then I'll set the name of the slice…and then I'll assign it with the single equals operator.…
Then, I'll use opening and closing…brackets without a number.…This means it's a slice.…If I were to put a number in, that would mean it's an array;…without, it's a slice.…After the brackets, I'll declare the type of the items…in the slice, and then I could assign the values…individually as I did before, or, as I did…with the previous examples with arrays,…I can use a pair of braces, and simply list the items.…I'll list red, green and blue.…
The size of the slice in this example…is inferred from the number of items in the list.…
