海外TECH	DEV Community	Introduction to `this`, `new` & OOP	https://dev.to/topcode007/introduction-to-this-new-oop-1o1b	Introduction to this new amp OOPHello I am going to explain what object oriented programming is and how it s implemented in JavaScript We ll go over the theory of OOP and discuss what the keywords this and new mean in regards to code A Gentle Introduction to OOPAt the highest level we can describe OOP as an attempt to package a set of data and functionality into one item that we can work with The idea is that information and functions that work on that information by manipulating it logging it deleting it etc should be a self contained package It s a data centric model This eliminates several problems such as the need for global variables that might conflict with one another and the spread of code across a file that makes it difficult to read and follow In JavaScript this package that we re trying to put all of our data and functions in will be a plain object The keywords this and new are signals to a developer that we are using object oriented programming They indicate that we are creating and working with packaged sets of information The idea of this this is closely tied to OOP It is a source of great pain for many developers even those with years of experience It behaves differently in JavaScript than it does in other languages We ll use this general idea as our guideline In JavaScript this inside a function is meant to reference the object that the function is a property of The rules in JavaScript are a bit odd but understanding the point of this and why it exists in programming languages should ease the explanation It s meant to draw the developer s attention to one single object When used the this keyword is basically shouting out that the main object this function is supposed to work on is this Examining this In JavaScript every function is called on some object and therefore this has a value in every function Let s start with a normal function call Useless this in Free Function Invocationfunction fn do something fn Although it seems as if fn is called freely not bound to any object it s actually stored by the JavaScript engine as a property on the global object In a browser the global object is window If we open up our browser s console and type in the code in the block above with the following line we can verify that fn is indeed a property of window console log window fn fn gt trueWe know that the equality operator when working on functions or other objects checks the reference so we can be certain that fn is exactly the same as window fn When we omit window JavaScript implicitly enters it into our code What does this mean for this Remember that according to our guideline this in a function is supposed to represent the object that the function is being called on In the case of simply calling fn that s exactly what we see function fn console log this fn gt Window frames Window postMessage ƒ … We see that this is equal to window So it follows our guideline of representing the object the function is being called upon The act of calling a function freely as we re doing here is referred to as a free function invocation The value of this in an FFI is the global object Why it s Useless HereAs we can see having this equal the global object isn t very useful If we want to set a variable on the global object from inside a function something we should really never be doing we can just omit the var let and const keywords entirely If we want to access something in the global scope we still don t need this If we ever did need access to the global scope we could always use window or whatever the global object is in the current environment Ideally this should be something like undefined inside a function invoked freely Unfortunately it s not and we have to deal with the issues it causes in terms of code readability and understanding We ve covered the useless case of this We ll never be using it this way but we should be aware of the fact that this functionality exists Let s move on to how this is actually used in OOP Method CallA function that is a property of an object is called a method Technically all functions are methods as free functions are implicitly turned into methods of the global object Let s look at a function that is explicitly a method of some object that we define const obj str Hello fn function console log this obj fn gt str Hello fn Function fn The function is a property of obj We see that this inside the function when we invoke obj fn is equal to the object obj This again meets our guideline that this in a function should be the object that the function is on Let s say we want to have a counter on obj We want a method on obj that will increment the counter const obj counter incrementCounter function this counter this logCounter logCounter function console log this counter obj incrementCounter gt obj incrementCounter gt obj incrementCounter gt We re starting to see the crux of object oriented programming The object is made into a self contained item which should be manipulated using its own internal methods Introduction to newnew is another keyword used in OOP new is used to invoke a function in a different way than we re used to The point of new is to indicate that we want an object returned by the function It indicates that we intend to use OOP and that the object the function returns is going to contain a packaged set of data and maybe methods to go along with that data The keyword also retains its original meaning when we use new we re always being returned a fresh newly constructed object with a brand new reference This object comes into existence inside the function function fn console log fn gt undefinedconsole log new fn gt fn Even though we have no code inside fn when invoked with new it still automatically returns a new object We ll go into these rules and nuances in the next lesson For now we see that new is closely tied to the generation of objects in OOP Note that the item we see logged to the console due to line above logs out fn If we log an object that was created using new the console logs out the name of the function that created the object and then the object This short bit of object oriented theory should have you primed for the next few lessons We will see the Rules to new in next blog Hope this blog would be helpful for your real life	2022-05-20 23:19:55
