Control Flow

Control Flow in Go is similar to most C family languages but has some novel differences. Classic structures like if and switch are present but their syntax is a little different from what you might be used to.

There are no ternary operators.

Notes

• if statements require an exact boolean expression. There is no "truthy" or "falsey".
• if statements may have a pre-expression similar to the first part of a for statement.
• switch statements do not require breaks and will not fall through by default.
• switch statements can have multiple values per case.
• Use the || "or" and && "and" operators for complex conditions.
• Use shorter variable names that still provide context for the value they represent.
