    Good stuff. You didn't mention immutability and encapsulation design principles. If for example you have a class with private fields, you can use getters to expose their values as copies to the public without the program being able to change the private field's value. Some datatypes are immutable, but others aren't like arrays, so this is a great use case of a getter to send a copy of an array (e.g using .slice() ) while protecting the real private array.

      But we can already send a copy of array without using getter right?

    • @devnullsrevenge

      @@swagathshetty The getter would return a reference to the original mutable array, unless you purposefully write logic to ensure it's a copy. This is why tricks like returning the array.slice() with no arguments are popular.

    I had some weird idea for what getters and setters were and now I understand it's basically using a method as an object's property

    The real MVP!! I was getting confuse on creating a setter and getter until I found this video. Thank you once again.
    I know this is not like c++ but I was wondering if we can also named the method set setFullName(newName) and get getFullName or it is better just a set fullname(newName) and get fullName()

    Question!
    what about more _simple_ mutations of an object? Maybe i just want to decrement a property, why do i require an argument when using the setter in that case?

    Great video. Very useful.
    I'd love to see how you'd tackle a complex form. Something with lots of conditional logic that saves different field values based on those conditions into a database. Also how you'd deal with retrieving the values back into the form to edit and resave them.
    I can all but hope 👍

    I would love if you would update your The Modern Javascript Bootcamp Course on Udemy. It really needs a big update like the one you did with the Web Developer Bootcamp at this point, due to all the changes that made a lot of the code to stop working.

    Short question: is there a way to make 'first' and 'last' as private properties in JS? Or in TS, maybe?

    I have a question, isn't it a performance issue when a getter is called multiple times instead of only once and returning that value instead of recomputing it every time

  • @phileze_
    @phileze_ Рік тому

    How did you assign first and last in the constructor when there is no property for that in the class please?

    • @lizavetakanapatskaya6963
      @lizavetakanapatskaya6963 Рік тому

      If I get you right, the answer is - the constructor of the Person class is accepting 2 values (on the very top - line #2): 'first' and 'last' and then we assign them like -
      this.first = first. and
      this.last = last (line #3 and #4).
      That means when we'll create new object (line #11) - everything we pass into brackets of "new Person()" will assign the first argument as our first name and the second argument - as the second name.
