There are numerous ways that you can declare and create arrays and slices in Go. This lesson will show you several and I talk about the advantages and disadvantages of one over another. After watching, you will better understand all of the possible ways you can declare/create as well as the idiomatic way.

These include:

  • var
  • the built-in function new
  • the built-in function make
  • Array and Slice literals

While it is not the main intent of this lesson, I do touch on some of the differences between slices and arrays.
