Object-oriented Programming in JavaScript: Made Super Simple | Mosh

Bro, you did in 1 hour what 3 different computer science profs of my university didnt manage to be able to in 3 years of studying - make me understanding why I write the code I have to write ... they only explain how to write the code on a OOP way but never WHY we do it that way

What is the name of theme/color code you're using?

I am starting to learn JS, looks to be a great video in Intermediate level . . .
I need to come back to learn the "Intermediate Level "

i love you mosh your a life saver.

You are super Mosh

how come the full course link is broken ?

Thanks a lot Mosh, it was truly informative tutorial

@programmingwithmosh isn't it the part about abstraction , encapsulation.

good

عالی سلطان❤️

Can you suggest a best book for javascript

Mosh we need the continuation

Awesome video! Why was there Arugula on the spaghetti?

Hi, good video. What software do you use to make those presentations??

You would be a billionare If you would get 1% of what ppl learned from u

Heads up for those coming to this tutorial in 2023, setting variables like shown in example:
let duration, startTime, endTime = 0;

will actually lead duration to be undefined and when you try to add seconds to it in stop function, it will produce NaN.

Correct way is: let duration = 0, startTime = 0, endTime = 0;

Now we also have classes 🎉🎉🎉

My solution for stopwatch problem using setInterval-

function StopWatch() {
let time = 0;
let id = null;
this.start = function () {
if (id) {
// throw error
console.log("cannot start again Try stop first");
} else {
id = setInterval(() => {
time += 0.1;
}, 100);
}
};
this.duration = function () {
console.log(time);
};
this.stop = function () {
// throw error
if (!id) console.log("cannot stop again Try start first");
else {
clearInterval(id);
id = null;
}
};
this.reset = function () {
if (id) {
clearInterval(id)
};
id = null;
time = 0;
};
}

let sw = new StopWatch();

You are the man! You explain things in a really simple way. Thank you for your work!

What a messed up tutorial. I went for Traversy Media's instead. Much relevant and understandable. This one is weird.

Loving the tutorials but for this video the music while your talking is a bit of distraction especially when your explaining complex one like differentiating the 4 cores. Love the solo piano tho :)

You made the hard to grasp so easy.

Hi Mosh! Really good video, just one thing.
Where you were talking about the ways to get the keys from the object, it's not a good idea use the "key in object" to do so. Its better to use hasOwnProperty.

Why?
Because the first one fo through the whole object (prototype chain and beyond) and the other one just seek on that particular object :D

what do you mean there is no concept of "classes" in javascript , lol?

music in the video is so noise, please don't put it again

Oh Goodness Gracious me What a Presentation👍👋✌ Even in premium paid courses No one teaches like this. Thank you very much GOD Bless you MOSH for your great service to the students community at large

can we say by creating objects with a constructor, we are actually using some type of encapsulation?

im so confused when he says in javascript we don't have concept of classes while we do have class in ES6.

Thank you❤️

So..

can't believe that Hamedani isn't persian from Iran!

Very usefull , thank you Mosh

Great tutorials. Can anyone explain what this does, or has Mosh taken it out of context?

Circle.call({}, 1);

In particular the 1.

Thanks

Hi mosh, what a great video, but I have a question, what is the difference between oop with function and oop with class in javascript?

Love your videos, Mosh ❤I did struggle with tutorials. What really worked for me were Books and Mosh`s Videos.
Edit: For those asking, I started learning with a basic book named Javascript In Less Than 50 Pages, which is very beginner friendly.
Then I improved my skills with another one named Head First Javascript Programming.
With those books I finally learned and wanted to share what worked for me.

never got it it's only me but JavaScript is really difficult for me. And that's my first language that I learn.

Amazing tutorial! Thanks a lot

Hi Mosh, great tutorials. I have a problem finding the live server to start programming your exercises, there is an alternative that you can suggest? or some other student can help me?

as a begginner i have no idea what is actually happening

To be honest....I need some enlightenment concerning the exercise, you declared them in a broader scope but assigned their values within the methods....I thought because of scopes the value assigned inside child functions will not affect that of it's parent...please explain to me
