LAMBDA EXPRESSIONS - Coggle Diagram

- - - - Create a predicate method
        
        No lambda
        
        static bool IsCheaperThan10(Book book) { return book.Price < 10; }
        
        var bookCollection = books.FindAll(IsCheaperThan10);
        
        Using lamda
        
        var bookCollection = books.FindAll(book => book.Price < 10);
        
        Instead of creating a new method we use a lambda expression
        
        book => book.Price < 10)
- - - - static int Square(int number) { return number * number; }
    - - Syntax one arg
        
        arg => expression
      - number => number * number;
        
        Func<int, int> squareFunc = number => number * number;
        
        int SquareFunc(int number) => number * number;
        
        Use a local function
        
        Assign the anonymous function to a Func so we can call it and have return value
      - Syntax no args
        
        () => expression
      - Syntax multiple args
        
        (arg1, arg2) => expression
