Summary
At this point, you know how Go differs from other programming languages. For instance, Go doesn't require you to write parentheses in conditions for if, for, or switch statements. But you always need to write braces ({}). You can chain if statements, and an else clause is optional. Crucially, you can declare variables within an if condition, and their scope is only within the if block. You can't access those variables outside the block, even in the same function.
Go supports switch statements, and you don't have to write a condition. You can use just case clauses. Unlike other languages, in Go you don't need to write a break statement at the end of each case clause to avoid running other case clauses.
By default, when Go enters into a case statement, it runs it and then exits the switch clause. To jump to the next case clause, use the fallthrough keyword. You can call a function from a case clause, and you can group multiple expressions in one case clause.
In this module, you also learned that in Go you use only the for keyword to write loops. But you can write infinite loops or while conditions. Go supports the continue keyword, so you can skip an iteration of a loop without exiting the loop.
Lastly, you learned about other Go control flows like the defer, panic, and recover functions. Go doesn't support exceptions. It deals with runtime errors by using a combination of the three functions.
