What is &+/2 in elixir?

Question

Saw this in elixir guide:

Enum.reduce([1, 2, 3], 0, &+/2)

What the heck is &+/2 ? I can't seem to google it for the life of me.

Answer 1

In this example you capture the module function +/2 . Capture operator & turns module function into anonymous one. Here it captures the +/2 , which is actually Kernel.+/2 . Read more here .
