What is “_,” (underscore comma) in a Go declaration?

Question

And I can\'t seem to understand this kind of variable declaration:

_, prs := m[\"example\"]

What exactly is \"_,\" doing and w

Answer 1

It is called the blank identifier and it helps in cases where you wish to discard the value that is going to be returned and not reference it

Some places where we use it:

• A function returns a value and you don't intend to use it in the future
• You want to iterate and need an i value that you will not be using
