Elixir 1.13.0 has come up with many improvements. In this article, we cover fewer of them with some code examples and use cases. Here, we cover the following 6 things.

  1. Different ways of using the new function Enum.slide/3
  2. Getting to know the IEX Autocompletion on sigils and structs and struct fields in an iex session
  3. Experiencing the improvement on Syntax Error Report
  4. Experiencing the Power operator ** from Kernel module
  5. How to use the new function Keyword.validate/2
  6. Newly added functions Task.ignore/1 and Task.completed/1

1. Add Enum.slide/3

It is used to slide single or multiple elements in a list. We can specify a single position or range of indices to be slid to the specified index. It also supports the negative index.

All the examples are directly copied from the documentation and created image graphics over the list.
