    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.

    But,
    If you use constructor function, then you can use #this keyword because it refers to our own object.

    Great tutorial. I had a little bit of trouble with the exercise but I eventually figured it out.
    One thing I did differently was in my "duration" getter, I added an 'if' clause to check if the stopwatch was running. If it was, I set the duration to the current lapsed time at that moment, then returned 'duration'. That way you would always be able to see the duration, even if you haven't stopped the stopwatch yet.

      Although we have surpassed the beta phase, but on the way we have realized that relying on developers is quite risky as a business, since we as founders have non-technical background.
      Deliberate delays, misguiding & disproportionate salaries are just a few problems which we encountered on our way to launch.
      After that I decided to take things in my own hands & got one of my dev. friend to oversee all the Tech part till I am confident of taking over the Tech.
      My goal is to understand all the stuff that's happening at coding level, & eventually manage the developers we have hired. And also to get my hands on coding if the doomsday arrives.

    Hi Mosh! Great tutorial, it really helped me a lot to understand the basics. I will definitely continue with the rest of your videos.
    But I found the example with increase() function a bit confusing. I am not skilled enough, so maybe I am mistaken, but at 34:15 - 34:42 the same result (number = 10, not 11 as you stated in video) will return (if we add "return" of course) because of operator i++, which returns a value before increment.

    • @ibtehaj95
      @ibtehaj95 2 года назад

      I'm sure you've found this out by now, but just to be clear for others, Mosh and you are both right in this regard. When you pass a variable as an input parameter to a function, its copy is being passed, not the original variable, hence any changes made inside the function will remain inside and never make out of that function.... unless you use a return statement to update the variable outside the function (as you said). To add onto this, this problem is solved by using pointers in C++, thru which you can pass the "reference" of that variable to a function and then no copy is created.

I think it's worth mentioning that before beginning the exercise at the end.. as a hint, people can take advantage of the Date() method and instantiate using new Date() (you can perform subtraction between date instances to get the time elapsed). For me, I had to do a quick google search and there were so many answers online but I figured this was the simplest so find the time elapsed lol.

    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;

      @@shreedharsharma4745 honestly mate, I can't learn with courses and stuff. I learned programming by trying out different stuff. It started with keybinders with Autohotkey (simple scripting language) and I just advanced as I tried out new stuff. Get yourself some random web page from the internet, maybe something from dribble and try to create your own copy of that website locally. Think abt stuff you would do differently. Check out some portfolios of devs and look at their projects. The best way to learn programming in my opinion is by trying.
      This video helped me because I already knew how object oriented programming works with other languages and I never really thought abt it in JavaScript. This video gave me a better understanding of how functions and objects etc work in JavaScript and helped me organizing my codebase in JavaScript projects :)

    This is a great video! I've recommended it to many of my classmates. Just a small suggestion, maybe in the example, instead of 'circle, radius, location...', you can use something easier to understand like 'user's info', 'apples', 'shopping list' etc. to make the learning process even more smoother. I know that circle is easy to understand already XD but every time I see radius and stuff like computeOptimumLocation, it takes me 1 second to react >

    Hi Mosh, first of all, I would thank you for your amazing videos. I have +3 years exp as a dev. What I like about your courses is your way of explanation. The way you teach is likely the way of the academic teaches but with a magic touch! Most instructors on RUclips ignore the identifications like what closures, abstraction, ...etc mean? and they are so important to know especially for the interviews!

    But the course is excellent, well organized and clean, totally recomended.

      Classes are syntactic sugar prototype inheritance in javascript and they do not function as classes in OOP languages. He is talking about the function under the hood.

      Alejandro Montes depending on what contexts and how the new object is used, it may require a lot binding of the "this" keyword.

    Think it's misleading that you mention that classes don't exist in JavaScript. In ES6 (released 3 years after this video), the `class` keyword can be used to declare classes in a way that's similar to classical OOP languages. Under the hood, it creates objects that are basically the same as the ones in the video, but it's a much nicer syntax.
    It'd be rare to see "classes" created in the 2 ways described in this video in modern JavaScript/TypeScript applications.
