expression-表达式 表达式(expression)是可以作为函数参数的,如:10*a; 语句(statement):不能作为函数参数,如:print(a)。 new test();是一条语句(statement)。i+1是一个表达式(expression),就像cron表达式、EL表达式、lambda表达式一样,不是statement。
console.log("Hello!"); } Declarations are loaded before any code can run.Function declarations load before any code is executed while Function expressions load only when the interpreter reaches that line of code. Similar to the var statement, function declarations are hoisted to the top of other...
You can omit the return type part of a lambda expression if the lambda body contains a single return statement or the lambda expression does not return a value. If the lambda body consists of a single return statement, the compiler deduces the return type from the type of the return expres...

If a QUERY expression (query_expression) consists of several QUERY specifications (query_spec), the TOP syntax element must only be contained in the first QUERY specification. If you use a ROWNO predicate, a LIMIT-clause or a CREATE VIEW statement, you cannot use the TOP syntax element....

Lambda syntax that defines an expression tree is called an expression lambda (as opposed to a statement lambda), and looks like this in C#: C# Copy Expression<Func<Integer, String>> expr = i => i.ToString(); IQueryable<Person> personSource = ... var qry = q...
A LINQ database provider (such as Entity Framework, LINQ2SQL or NHibernate) can take such an expression tree and map the different parts into the SQL statement at the beginning of this section. Here’s how: ExpresssionType.Call to Queryable.Where is parsed as a SQL WHERE clause ...
