海外TECH	DEV Community	Is "this" really that complicated in JavaScript?	https://dev.to/chuckchoiboi/is-this-really-that-complicated-in-javascript-4o3h	Is quot this quot really that complicated in JavaScript this keyword can be one of the most confusing monsters in JavaScript Especially those who didn t learn JavaScript as their first programming language find it pretty confusing as it behaves differently in JS compared to the other languages And many programmers rely on libraries like jQuery so they learn how to use it but don t get to fully comprehend its fundamentals Well let me show you how this isn t as confusing as you think What is this in JavaScript MDN Web Doc explains that this is A property of an execution context global function or eval that in non strict mode is always a reference to an object and in strict mode can be any value In most cases the value of this is determined by how a function is called runtime binding It can t be set by assignment during execution and it may be different each time the function is called To put it simply this is a keyword used to reference the execution context We could think of it as whoever it is that calls the function So this typically refers to the object that is invoking its method In JavaScript any value can be determined when it is defined or when the function is called The latter is the case for this keyword usually in the case of Implicit binding With Implicit binding the value of this is determined based on the execution context But this behaves differently if the function being invoked as an arrow function or if you are using strict mode introduced in ES And there s Explicit binding which you can explicitly bind this keyword to an object you pass as an argument for call bind and apply methods Let s dive in deeper to each of them Object MethodTake a look at the following code var hi myName Slim Shady myNameIs function console log this myName hi myNameIs prints Slim Shady The above code s hi object has a method myNameIs which logs myName of this in the console When hi object invokes its method like the following hi myNameIs the object who called the function is hi which makes this to be implicitly bound to hi object Hence the console will log myName of the object Slim Shady A simple way to look at it is that whatever is on the left side of a dot notation of a method being invoked is the object that this will be referring to How about this example though function whatIsThis console log this whatIsThis prints Window Hmm we just discussed that an easy way to understand this keyword in object method invocation is paying attention to the left side of dot notation But this time whatIsThis is a function defined using function declaration and we can execute it without an object which logs this as the window object Sounds pretty confusing right Well when we declare a function we are making it a global function available to the global object so the function s containing scope is the global object Window Another way to execute whatIsThis is window whatIsThis Look at that window is on the left side of whatIsThis This brings me to the next point this in global context Global ContextAs we discussed when a method inside an object is executed by the object this refers to the object But what happens if I try to simply log this into console Give it a try in your browser console log this prints Window Looks like this refers to window object By default this refers to the global object Window in browser environment If we want to understand why it is ask yourself or Google what the window object is If we take a look at MDN Web Docs again it explains The window object is the Global Object in the Browser Any Global Variables or Functions can be accessed as properties of the window object When we add this to your browser console your global environment Window is executing the expression this so the window object is being referred to in this global context Back to the Slim Shady example here s a function created using the myNameIs method in hi object earlier var hi myName Slim Shady myNameIs function console log this myName var hisNameIs hi myNameIs hisNameIs prints undefinedInteresting hisNameIs function logged undefined in the console Let s try to understand what happened at the line var hisNameIs hi myNameIs First hi myNameIs is a method a property containing a function definition We simply declared a global function named hisNameIs by using var and initialized it with the function definition from hi object passed Second global functions are stored as properties in the window object When we invoke the global function hisNameIs it is the same as window hisNameIs The window is the object that is executing its method hisNameIs so this is now referring to the window object window object does not have a property named myName so it will return undefined In conclusion this will refer to the global object in global context Strict ModeJavaScript was first introduced in as Mocha which took days to develop by a Netscape programmer named Brandon Eich It would be surprising if the language came out to be perfect in days of development right The language has evolved to today s version ES with the language designers attempt to correct the flaws in the past versions Its legacy features were not possible to be removed in order to maintain the backward compatibility which is why strict mode was introduced in ES to opt in to correct the early language flaws this keyword is one of them It behaves differently when you opt into strict mode function whatIsThis use strict console log this whatIsThis prints undefinedIn strict mode this keyword will default to undefined in function invocation It is likely that this keyword was not meant to point to the window object as you can simply use window keyword to do so In ES bind method was introduced to explicitly set the function s this regardless of how it is called You can pass an object as an argument when using bind method and the function s this keyword will refer to the object no matter how the function is invoked Bringing back the code from earlier using bind method this time we can now create a new function with object passed explicitly like this var hi myName Slim Shady myNameIs function use strict console log this myName var hisNameIs hi myNameIs bind hi hisNameIs prints Slim ShadyBoom Even with the strict mode hisNameIs function s this will refer to the hi object passed no matter what call and apply are basically the same which you can pass additional arguments to the function The three methods are slightly different which you can read more about in this blog post Arrow functionthis inside an arrow function behaves a bit differently compared to the one inside a function declaration or a function expression Arrow function was introduced in ES as an alternative to a traditional way of defining function Let s compare these two objects using the different versions of function using regular function as callback inside forEach var oldPhone owner Chuck apps Facebook YouTube Uber useApps function this apps forEach function app console log this owner is using app this refers to the window object oldPhone useApps prints undefined is using Facebook prints undefined is using YouTube prints undefined is using Uberoldphone useApps function iterates each of the apps using forEach with a regular function passed as a callback function However the callback function inside forEach method does not bind to the original object Instead it will bind to the global window object thus this owner returns undefined This could be very inconvenient if we were doing something similar as a class There are two ways to fix it though forEach method takes an optional argument thisArg in addition to the callback function like this arr forEach callback thisArg Or we can use an arrow function as a callback to utilize its lexical scoping using arrow function as callback inside forEach var newPhone owner Chuck apps Facebook YouTube Uber useApps function this apps forEach app gt console log this owner is using app newPhone useApps prints Chuck is using Facebook prints Chuck is using YouTube prints Chuck is using UberVoila This time the callback function s this referred to newPhone and logged this owner as Chuck Arrow function allows you to write functions in a cleaner way and they have lexical scope I mentioned earlier which means that they will inherit the scope from its parent The callback function nested inside the forEach method above inherited the scope from its parent useApps which is newPhone object Because of this nature The value of this inside arrow functions is determined when the arrow function is defined unlike the typical situations from earlier I personally think that this inside an arrow function is the most confusing part of this keyword but it simply inherits the scope from its parent NOTEbind call and apply are not compatible with arrow functions Arrow functions will inherit the scope from its parent regardless ConclusionTo conclude let s summarize how this works in JavaScript this is a keyword used to reference the execution contextIn method invocation the object that is invoking the method would be the execution context this will refer toIn global context like regular function invocation this will default to the global objectIn strict mode this keyword will default to undefined in regular function invocation You can use bind call or apply to explicitly bind an object to a functionAn arrow function will inherit the scope from its parent so this inside an arrow function will follow its parent sbind call and apply do not work for arrow functionsHope this was helpful resource for you to understand how this works in JavaScript Feel free to comment below if you have any questions or notice any inaccurate information and I will respond as soon as possible Follow me on Clubhouse
