Null container in go

[Humble]

Lets start with null

We have seen many times in go packages that, variables are initialized as “_”. That basically means:

Underscore is a special character in Go which acts as a null container. After importing or after assigning a variable in Go, if we are not using it, go compiler will throw an error. To avoid that, we are storing reference of that package/variable into _, and Go compiler will simply ignore it.

Aliasing a package with an underscore which seems to do nothing is quite useful sometimes when you want to initialize a package but not use it.
