Go if and switch

The if statement in Go is similar to most programming languages, except for a few quirks in Go: The expression does not require parentheses (), and the opening brace { cannot start on a new line.

if booleanExpression1 {
    //...    
} else if booleanExpression2 {
    //...    
} else {
    //...
}

The switch statement in Go is also similar to most programming languages, but it has a few quirks in Go: It does not require an explicit break statement, and it automatically terminates once a case matches.

switch variableName {
   case condition1:
       //...
   case condition2,condition3,condition4: //test multiple values that might satisfy the condition simultaneously, separated by commas
       //...
   case condition5:
       //...
   default:
       //...
}
