Explanation: The describe method is added to the Book prototype, meaning all instances of Book share the same describe method. This is more efficient than if describe were defined inside the constructor, which would result in a new function for every book instance. 3. Return Values Best Practic...
), in production it is very nearly mandatory for reasons just like this. But nevertheless, constructors that do not take into account the possibility of being called without thenewkeyword are a potential problem.
The object is a simple JavaScript Object - with special keys (also referred to mutator keys). A mutator key is a key:value pair that has a special meaning and is used differently by the Class constructor. The following keys in your config object are considered mutator: constructor The ...

In such a case, with only a constructor like that one above, the client would need to pass null for the middle name String and zeroes or some other number without meaning. The numeric types could be reference types rather than primitives, but the clients would still need to pass null for...
This wouldn't be a breaking change in existing TypeScript/JavaScript code(not sure actually. I'd guess not?) This wouldn't change the runtime behavior of existing JavaScript code This could be implemented without emitting different JS based on the types of the expressions ...
This is really useful because it provides more context and meaning to your code. If you want, you can also provide one or more constructors to your Enum as it also supports constructor overloading like normal Java classes. This is very different from the enum you have seen in C or C++...

These tests are located in the tests/tests.cpp file. Usage Namespacing Every class and enum in CTML is enclosed in the CTML namespace. For instance, the Node class would be under CTML::Node. Chaining Most methods for operating on CTML::Node instances are chainable, meaning that you may ...
