Using immutable locals: Uses less horizontal space but more vertical space than the "anonymous temporaries" template. Preferable over the "anonymous temporaries" template if the when expression is in a loop--in that case, regex definitions should be placed outside the loop. im...

A command-line launcher is a handle tool which allows one to open WebStorm using the command-line. It can easily be created by using the menus Tools > Create Command-line Launcher... After selecting the option, you will be presented with the "Create Launcher Script" prompt for a l...

A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case, and the variable being switched on is checked for each switch case. A switch statement is often more concise and understandable than if...else if... else.. statements when testing m...

No Longer supported: Get ["/"] = parameters => { return View["index"]; }; Changed to: Get("/", parameters => { return View["index"]; });

try...catch block is for handling exceptions, remember exception means the thrown error not the error. try { var a = 1; b++; //this will cause an error because be is undefined console.log(b); //this line will not be executed } catch (error) { console.log(error); //here we handl...

It's a good practice to scope patches using Refinements, but sometimes it's nice to load it globally (for example in development, or testing). Say for example you want to start a console, require your library, and then have the patched methods available in the global scope. You couldn't do this wit...

A synchronous producer-consumer solution ensures that the consumer reads every data item written by the producer exactly one time. Asynchronous solutions allow the consumer to sample the output of the producer. Either the consumer consumes the data faster than it is produced, or the consumer consume...

Some applications may want to create so-called "Fire & Forget" tasks which can be periodically triggered and do not need to return any type of value returned upon completion of the assigned task (for example, purging old temp files, rotating logs, autosaving state). In this example, w...

It is often necessary to execute a long-running task and use the result of that task once it has completed. In this example, we will create two classes: One which implements the Callable<T> interface (where T is the type we wish to return), and one which contains a main() method. AsyncValueT...

To leverage distributed cache, you'll have to reference one of the available implementations : Redis Sql server For instance you'll register Redis implemention as follows : public void ConfigureServices(IServiceCollection services) { services.AddDistributedRedisCache(options => ...

While good software design often maximizes code reusability, sometimes it can be useful to define asynchronous tasks inline in your code via Lambda expressions to maximize code readability. In this example, we will create a single class which contains a main() method. Inside this method, we will us...

Character literals provide the most convenient way to express char values in Java source code. A character literal consists of: An opening single-quote (') character. A representation of a character. This representation cannot be a single-quote or a line-break character, but it can be an escap...
