As in most every language, Scala's if evaluates a conditional expression, then proceeds to a block if the result is true or branches to an alternate block if the result is false. A simple example.
和大多数语言一样，Scala的if测试一个条件表达式，然后根据结果为真或假来跳转到响应语句块中。

For example, if the expression doesn't use the last function then it is not necessary to do look-ahead processing to determine how many elements there are in the context list.
例如，如果表达式不使用last函数，那么就不必执行先行处理来确定上下文列表中有多少元素。
As the name implies, each if-then rule consists of a Boolean expression that determines whether to execute one or multiple actions specified in the then clauses.
和其名称一样，每个if - then规则包含一个Boolean表达式，用于确定是否执行在then子句中指定的一个或多个操作。
