Let’s create a new is an anonymous function we define and pass as an argument to unwrap_or_else. We’ll be covering closures in more detail in Chapter 13. What you need to know for now is that unwrap_or_ else will pass the

range that includes both values. PDF conversion courtesy of www.appsdissected.com Functions and Closures Use func to declare a function. Call a function by following its name with a list of arguments hasAnyMatches(list: numbers, condition: lessThanTen) Functions are actually a special case of closures: blocks of code that can be called later. The code in a closure has access to things like variables writing closures more concisely. When a closure’s type is already known, such as the callback for a delegate, you can omit the type of its parameters, its return type, or both. Single statement closures implicitly

omits its upper value, and use ... to make a range that includes both values. ​ Functions and Closures Use func to declare a function. Call a function by following its name with a list of arguments [20, 19, 7, 12] 13 hasAnyMatches(numbers, lessThanTen) Functions are actually a special case of closures. You can write a closure without a name by surrounding code with braces ({}). Use in to separate T Rewrite the closure to return zero for all odd numbers. You have several options for writing closures more concisely. When a closure’s type is already known, such as the callback for a delegate, you

For examples of using the service container in the service container, including controllers, event listeners, filters, queue jobs, and even route Closures. So, to get an implementation of a contract, you can just "type-hint" the interface in the constructor

the AngularJS external webpage, and many external apps, are written in a style that freely uses closures, favors functional inheri- tance, and does not often use JavaScript types. Google follows a more not discussed further in this style guide. (But if you want further reading: Mar- tin Fowler on closures, much longer description, appendix A of the closure book has a good description of inheritance patterns
