海外TECH DEV Community Brainwash yourself everyday to success!🧠😍 https://dev.to/evansifyke/brainwash-yourself-everyday-to-success-114p Brainwash yourself everyday to success Hey folks Here is a tip on how to brainwash yourself to success ️Alter your reality to become a developer If you don t have enough hours to sit down and code find other ways to learn Some of you don t have the time to code because you have a family you have school and you have work Whatever your reason is there are still ways for you to learn I wouldn t tell you to stop coding I still need you to code every day as much as you can but here s how you can double triple or even quadruple your learning If you re at your computer while you re taking a break from coding there are YouTube videos that talk about code and maybe it ll even give you ideas to implement once you get back to work Anytime you re stepping away from your computer to take care of life immerse yourself in anything that has to do with coding If you drive for one to two hours a day you can listen to coding podcasts There are some good ones out there where that just talk about coding and that can help while you re away from your computer If you re a parent that has to take care of housework like washing dishes or cleaning the house you can also watch Youtube videos or listen to podcasts while you re doing that No matter what you do in your winding down time try watching shows like Silicon Valley or Mr Robot You may not learn coding through those like you would with podcasts or Youtube videos but it ll keep you entertained while being pumped up to continue learning to code When it s time to sleep your brain will finish processing all the information you took in throughout the day and it will all help you for your coding session the next day Do that every day and you ll start to connect more with the reality of being a software developer making you want to do things right Keep going on your journey and immerse yourself into being a software developer and you ll get there If you want to get immersed with help along the way get help from me and my team ConclusionGet more of this articles on www melbite comIf this was helpful leave a comment and a like Happy coding 2023-01-13 19:35:39
海外TECH DEV Community Design Patterns in JavaScript https://dev.to/thesanjeevsharma/design-patterns-in-javascript-3fmb Design Patterns in JavaScriptHey It has been a few years now since I started coding professionally I ve always heard the term Design Patterns in conversations but never really tried to learn them It was only recently when a senior dev reviewed my PR at work and left a comment which said try to make this a singleton That led me to finally do some digging on this topic I went through a bunch of resources like crash courses articles and YouTube videos To my surprise I found that I have been using some of these patterns unknowingly I am pretty sure you ll feel the same too There were definitely some new ideas patterns which I found useful In this post I ll try to cover some of the patterns which will surely help you to become a better dev and even arouse your curiosity to learn more such patterns What are Design Patterns Design patterns are battle tested blueprints for common software architecture problems They provide an abstract concept to solve a problem It s up to the developer to build upon them and come up with the actual solution Unlike algorithms these patterns do not provide clear steps to solve a problem These are just design ideas that you can extend further according to your needs Some of these patterns are listed below Singleton PatternSingleton pattern ensures that a class has only one instance and that instance is accessible globally throughout the application The imports of this Singleton all reference the same instance class LocalStorage constructor if LocalStorage instance LocalStorage instance this return LocalStorage instance setItem key value save to some storage console log Item saved key value getItem key console log Getting item key from storage get from storage and return const store Object freeze new LocalStorage export default store Implementing your own wrapper around local storage is a good example of Singleton pattern We d want to use the same instance app wide Here we create an instance of LocalStorage and export it There s no way to create another object of this class Even if they tried constructor would stop them as it checks if an instance already exists or not Finally Object freeze is cherry on the cake It ll prevent any modifications to our object Uses Gain global access point to a single instance A singleton is only initialized once when it s requested Therefore it saves memory space Disadvantages It s hard to write tests for singletons as we cannot create new instances every time All tests depend on a single global instance Proxy PatternProxy pattern let s you provide a substitute wrapper for a target object Using this pattern one can intercept or redefine all the interactions with the target object JavaScript has in built Proxy and Reflect objects to implement this pattern const target name John age const handler get target key gt console log Getting key key return target key set target key value gt console log Setting value on key key target key value return true const proxyObject new Proxy target handler console log proxyObject name In the above code we provide a target object and a handler object to the Proxy The handler object can be used to overwrite implementations of object methods like get set has deleteProperty etc Alternatively if we wish to not modify the behavior of these methods like in the example above we can use Reflect It has the exact same functions available const handler get target key gt console log Getting key key return Reflect get target key set target key value gt console log Setting value on key key return Reflect set target key value Uses Access controlLogging requestsCachingLazy initializationDisadvantages It could lead to performance issues The code might get complex with the introduction of too many proxies Observer PatternThe observer pattern is a design pattern in which an object called the subject or publisher maintains a list of its dependents called observers or subscribers and notifies them automatically of any changes to its state This allows multiple objects to be notified when the state of another object changes without them having a direct reference to one another A simple example of this pattern would look something like this class Button constructor this subscribers subscribe fn this subscribers push fn doSomething const data x this notify data notify data this subscribers forEach fn gt fn data class EventHandler listener data console log Received data const button new Button const eventHandler new EventHandler button subscribe eventHandler listener button doSomething Received x In this example Button keeps track of all its subscribers and notifies them of any change by calling notify method Uses This pattern can be used when change in state of one object is important for other objects and these objects are not known beforehand Disadvantages This might lead to some performance issues in case of too many subscribers or some complex code in the notify function The order in which these subscribers get notified cannot be predicted Factory PatternThe factory pattern is a design pattern that provides a way to create objects without specifying the exact class of object that will be created Instead a factory class function is responsible for creating the objects IMO This is the simplest of all the patterns discussed here There s a high chance that many of you are already using it class Car constructor make model this make make this model model class Truck constructor make model payloadCapacity this make make this model model this payloadCapacity payloadCapacity function vehicleFactory type make model payloadCapacity switch type case car return new Car make model case truck return new Truck make model payloadCapacity default throw new Error Invalid vehicle type type const car vehicleFactory car Toyota Camry console log car Output Car make Toyota model Camry const truck vehicleFactory truck Ford F console log truck Output Truck make Ford model F payloadCapacity Instead of accessing the Car or Truck classes directly we delegate that task to our factory function Uses Can be used almost anywhere without any sort of overhead Enforces DRY Disadvantages I don t see any Prototype PatternThe prototype pattern is a design pattern that allows objects to be cloned or copied rather than created from scratch The Prototype design pattern relies on the JavaScript prototypical inheritance This pattern is used mainly for creating objects in performance intensive situations An example of the prototype pattern in JavaScript is a prototype object that represents a basic shape such as a rectangle and a function that creates new shapes based on the prototype const shapePrototype width height area function return this width this height function createShape shape const newShape Object create shapePrototype newShape width shape width newShape height shape height return newShape const shape createShape width height console log shape area Output const shape createShape width height console log shape area Output The createShape function takes an object as an argument which is used to set the width and height properties of the new shape The new shape object inherits the area method from the prototype You can verify this by checking the prototypes of the objects console log shapePrototype proto This is for you to find out console log shape proto Output area function return this width this height height width console log shape proto proto shapePrototype proto Output trueUses Memory efficient as multiple objects rely on the same prototype and share the same methods or properties Disadvantages In case of a long prototype chain it s hard to know where certain properties come from In conclusion design patterns are a powerful tool for organizing and structuring your code making it more readable maintainable and reusable The five patterns covered in this article are just a few examples of the many design patterns available in JavaScript By understanding these patterns and how they can be applied you can improve the quality of your code and make it more robust and efficient I hope this article has been helpful and informative I will continue to write about other design patterns in the future and feel free to connect with me on LinkedIn and Twitter where I share my thoughts and updates about my work and articles Thank you 2023-01-13 19:32:46
