海外TECH	DEV Community	🌀 Mixins in Typescript 🍀	https://dev.to/aravindvcyber/mixins-in-typescript-3jk3	Mixins in Typescript Mixins is a popular way of building up classes from reusable components by combining simpler partial classes In this article we are trying to demonstrate how we can use them in typescript Identify the Base Class We will start this by creating a base class like the below one class Book name constructor name string this name name Define a type definition focusing on our base class Define a type definition which is used to declare that the type being passed is nothing but a typical class type Constructor new args any gt Class expression way to define a mixin Define the factory function which will return a class expression this function is what we call Mixin here function Pages lt TBase extends Ctr gt Base TBase return class Pages extends Base pages setPages pages number this pages pages get Pages number return this pages Time to use the mixin to derive classes ️Let us use this newly created mixin to create a new classes as follows const PagedBook Pages Book const HP new PagedBook Harry Potter and the Sorcerer s Stone HP setPages console log HP name HP Pages const AW new PagedBook Alice s Adventures in Wonderland AW setPages console log AW name AW Pages In the above example this many sound weird at first sight that the same could be easily defined in the earlier base class itself but what we have achieved is that we are able to generate new subclass by combining partial class at runtime based on our requirement And hence it is powerful Constrained Mixins We can also make our Ctr type defined earlier more generic by using the below changes type GenCtr lt T gt new args any gt T type BookCtr GenCtr lt Book gt But why do we need to use this new generic constructor this is to make sure we can constrain by choosing the right base class features before we can extend with our mixin function Pages lt TBase extends BookCtr gt Base TBase return class Pages extends Base pages setPages pages number this pages pages get Pages number return this pages The above works the same way as the previous mixin but we have just demonstrated the use of constraints by using mixins to build classes const PagedBook Pages Book const HP new PagedBook Harry Potter and the Sorcerer s Stone HP setPages console log HP name HP Pages const AW new PagedBook Alice s Adventures in Wonderland AW setPages console log AW name AW Pages Another example Another example to add more notes by what we just meant type AuthorCtr GenCtr lt setAuthor author string gt void gt function AuthoredBook lt TBase extends AuthorCtr gt Base TBase return class AuthoredBook extends Base Author name string this setAuthor name In the segment above we have created a type which expects the base class to have a method setAuthor which takes a param author so that the mixin could be applied to extend the base classes This is one of the ways to create a constrained mixin Why do we need to add constraints we can identity the constraint it will help us write the mixin easily targeting the required features with the right set of dependancy at the same time second one this is that typescript we do this everywhere making well defined types so that we are may easily understand the block at the same time tsc will always remind us when we commit error besides giving us inference while coding This also let us define abstract mixins which are loosely coupled targeting only the specific features and can be chainned as per the necessity as in the below example class Novel name author constructor name string this name name setAuthor author string this author author about string return this name by this author The above code snippet used a raw Novel class here we can do some mixins to achieve the desirable effects First let us define them as follows type Authorable GenCtr lt setAuthor author string gt void gt function AuthoredBook lt TBase extends Authorable gt Base TBase return class AuthoredBook extends Base author fname string lname string this setAuthor fname lname type Printable GenCtr lt about gt string gt function PrintBook lt TBase extends Printable gt Base TBase return class PrintBook extends Base print return this about In the above code snippet we defined couple of mixins which is loosely coupled with any base class as it only expect specific methods to mix amp enhance it const StoryBook AuthoredBook Novel const PrintableBook PrintBook StoryBook const Sb new PrintableBook Gulliver s Travel Sb author Jonathan Swift console log Sb print What is cool about using mixins it that the order in which the chaining occurs is not important still the results will be consistent since the partial class features mix one after other as they are applied const PrintableBook PrintBook Novel const StoryBook AuthoredBook PrintableBook const Sb new StoryBook Gulliver s Travel Sb author Jonathan Swift console log Sb print Original post at Dev Post	2022-02-13 18:50:05
海外TECH	DEV Community	Do you know Javascript ?	https://dev.to/manas_dev/do-you-know-javascript--39k4	Do you know Javascript We already know that javascript is single threaded but the way it works is totally different from other programming languages like C and Java The Event LoopJavascript has a runtime model which is based on an event loop It s responsible for three things Executing the code Collecting and Processing Events Executing Queued tasks actually sub tasks Stackfunction foo b let a return a b function bar x let y return foo x y const baz bar assigns to bazIn the above example the order of operation will be in the following manner When bar is being called the first frame is created which was containing references to bar s argument and local variables When bar calls foo a second frame is created and pushed on top of the first one containing references to foo s arguments and local variables HeapObjects are allocated in a heap which is just a name to denote a large mostly unstructured region of memory QueueA JavaScript runtime uses a message queue which is a list of messages to be processed Each message has an associated function that gets called to handle the message At some point during the event loop the runtime starts handling the messages on the queue starting with the oldest one To do so the message is removed from the queue and its corresponding function is called with the message as an input parameter As always calling a function creates a new stack frame for that function s use The processing of functions continues until the stack is once again empty Then the event loop will process the next message in the queue if there is one Adding MessagesThe function setTimeout is called with arguments a message to add to the queue and a time value optional defaults to The time value represents the minimum delay after which the message will be pushed into the queue If there is no other message in the queue and the stack is empty the message is processed right after the delay However if there are messages the setTimeout message will have to wait for other messages to be processed For this reason the second argument indicates a minimum timeーnot a guaranteed time const seconds new Date getSeconds setTimeout function prints out meaning that the callback is not called immediately after milliseconds console log Ran after new Date getSeconds seconds seconds while true if new Date getSeconds seconds gt console log Good looped for seconds break Final WordsThe above article codes are being taken from MDN docs about the event loop	2022-02-13 18:21:09
