Hi Hitesh, Hope you are doing good and just felt like telling you what my mind says about your lectures explanation is crystal clear and content you are providing is good Most important one is even if I'm watching continuously for hours together I'm not feeling bored and not losing the interest. i think this happens with every one for sure. fun learning it. Thank you:)

@lohithkumar8257 6 лет назад

Successfully completed my assignment in 2 min...All credit goes mr.hitesh sir....thanks a lot

@kukutlaashokinformation3144 4 года назад

Really super explanation when I watcheched about "this" by other tutorials I haven't understood, but after watching this really I got full picture in my mind. Thank you very much.

@clairecrabtree6821 4 года назад

YES! That has been my problem trying to learn code. The same word is used over and over and I cannot tell if it a different element or not. Thank you for pointing that out!!!

@ManishJangir 6 лет назад

If you don't mind, I can tell "this" in 3 lines. AS LONG AS YOU DON'T USE "call, apply and bind", whatever is there before the called function is its "this". a.b.c() // a.b is "this" in function c abc() // nothing is there, window is "this" In case of using call, apply and bind, the first argument is "this". Ultimately determine "this" by who is calling the function. As simple as that. 😃 Great series! Thanks a lot Hitesh for helping people and this awesome work.

@michellejanay4704 Год назад

Hi, I just wanted to say, thank you for using words like "fun" and "exciting" to describe JavaScript. I immediately subscribed due to your positive mindset! Too often people talk about how much they hate it or how hard it is, but I agree with you! It IS fun :D

@syedakib3534 4 года назад

@voidvision1549 4 года назад

Hitesh Sir , Really thanks a lot .. Your tutorials are the best tutorials I've ever seen.

@mayanknagpal5989 4 года назад

instead of this.meetings we could have simply used task.meetings, to get rid of the scope problem. Github source: we use this. to ensure that after changing your variable name e.g. from user to something your code still works. Other than that, I imagine that (on some browsers) there may be some performance gain too, since with user.name browser has to lookup in context outside your function while using this.name sticks to current context.

@official.mhm13 4 года назад

You made my confusion clear at 11:34 Thanks a lot

@prasannapilankar6260 4 года назад

Best video on this keyword,I've seen so far on the RU-vid most probably bestest one🤘🤘🤘

@pavantejavydhik7354 6 лет назад

hey Hitesh, please help by making a video to understand this keyword in Java as well, pls, your teaching is best approach to understand tricky/neche topics pls

@stringsc120 5 лет назад

I fixed the logical problem by removing the default value of meetDone then change - by + in the meetDone function body and finally I can substract todo.meetings - todo.meetDone in the getSummaryOfDay function. It lead to the same result with different approach.

//Assisnment //Handle meeting done //Create a function that can reset entire day. let myTodos1 = { day: 'Monday', meetings: '5', meetsdone: '7', addMeetDone: function (num1) { this.meetsdone = (this.meetsdone + num1) }, reset: function () { this.meetings = 5; this.meetsdone = 7; } } myTodos1.addMeetDone(12); myTodos1.reset(); console.log(myTodos1);

@aiswarya5848 5 лет назад

What is the difference between using myTodods.meetings and this.meetings inside the function??

@balachanderharivarsha9757 5 лет назад

I have the same doubt. Both are giving the same output.

@DurgaPrasad-zo2lq 3 года назад

one doubt hitesh, this keyword is updating the key meetings is it correct? when you called the second function it logged the updated meetings value.

@user-dl6et4cn9w 5 лет назад

Hi sir, first of all thank you so much for these wonderful videos really helped me a lot I have a question I am trying this keyword with function inside the method but it is not working

@gelfordpenaranda4213 3 года назад

I tried to use arrow function but the result was an empty object? Is there difference ? let myTodos = { day: 'Monday', meetings: 0, meetingDone: 0, addMeeting : () => { console.log(this) }, }; myTodos.addMeeting()

@_echoheim 4 года назад

let work = { day:'mon', meetings: 0, done: 0, addmeeting: function(todo , meet = 0) { this.meetings = todo.meetings + meet } } console.log(work) work.addmeeting(work, 4) console.log(work)

How does scope play a role in the "this" keyword. Please explain. I got confused when you said scope.

@GoutamReddydazz 6 лет назад

In php properties of class has no $ signs so it can be easily detected the use of $this-> keyword in PHP oops . i like php syntax because it helps me to understand programming patterns .

var person = { firstName:"John", lastName:"Doe", age:50, eyeColor:"blue", fullName: function(){ document.write("Jhon Doe") } }; document.write(person.fullName()) jondoeundefined can any one please correct me on this

@azharjamal7334 5 лет назад

I guess its because you are using print statement inside the "fullName" function and again you are using the print statement outside the object. I have used the same code and i got the following result. var person = { firstName:"John", lastName:"Doe", age:50, eyeColor:"blue", fullName: function(){ return 'John Doe' } }; console.log(person.fullName()) Output: John Doe
