What is the use of GO in SQL Server Management Studio & Transact SQL?
SQL Server Management Studio always inserts a GO command when I create a query using the right click "Script As" menu. Why? What does GO actually do?

It is a batch terminator, you can however change it to whatever you want

Just to add to the existing answers, when you are creating views you must separate these commands into batches using go, otherwise you will get the error 'CREATE VIEW' must be the only statement in the batch. So, for example, you won't be able to execute the following sql script without go
create view MyView1 as
select Id,Name from table1
go
create view MyView2 as
select Id,Name from table1
go
select * from MyView1
select * from MyView2
