your student

[@vijaynavale3919]

Please deeply cover these proto and prototype part what is difference between them and how every thing becomes object in Javascript.

[@kevinthomas2406]

U n

[@divyarawat668]

Can u please tell me about the plugins needed for javascript??
On pressing !+ Enter ,,the syntax program is not opening...

[@Sisyck]

I finally understood how the New Keyword works. Thank you Hitesh!

[@srijithkaladharan5716]

Hitesh.. Can you please tell us how is it different from class and when should we use this way rather than a class??

[@kaushikshandilya8560]

Sir I have a question, I was visiting MDN for references and I found a section called "polyfill" and there is a syntax as
if(!Array.prototype.fill) {
Object.defineProperty(Array.prototype, 'fill', {
....
..
And so on
....
My question is the 1st line.... What it really means ? I m just jumbled. Please help

[@songrada1]

you didn't tell what happens if we asign variables to window object before calling the function without new word. For example window.firstName='regularname'

[@BadalKumar-pi7ud]

Your way of teaching is simply amazing!

[@jyeshbatra1887]

Sir is this course is enough to learn ReactJs framework??
btw great learning till now thank you so much for this.

[@hill-ar-ious]

If not using "new" keyword, and then "this" keyword is pointing to empty object in node, so in node empty object is defined as --> {} like this, so instead of giving output as "undefined" why didn't it gave as "{}" ?

[@Ata-r5r]

have you figured it out?

[@hiteshupreti4250]

But if you change to this:
var User = (firstName, courseCount) => { ....};
var hitesh = new User("Hitesh", 4);
it is showing error:
TypeError: User is not a constructor
at Object. (D:\HiteshChaudhary_javascript\Firstapp\11Newkeyword.js:9:14)
Why????

[@cannenschilling3455]

Because arrow functions can not be used as constructors. This is a late response but leaving it here for anyone else who's wondering.

[@sheersho]

Is there any discount codes applicable on his Data Structure with Python course?

[@karmjeetsaroj4877]

hi
i just have this code
const obj = {
name : "abc",
getname: function(){
console.log(this.name)
}
obj.getname();
const getname = obj.getname; *****
getname();
:::::: then there is a error this.name undefined comes >>>>How
is it because of the ***** code line is there somthig wrong if it is then what it is

[@rahulgothwal7150]

Happy Independence day...!

[@lakshitvashisht5703]

Interesting videos ! Worth it

[@Sushil2874]

Very nicely explained.... 👌

[@rbk.technology4747]

In every video u do a marketing and a free ad about your website LCO. Which is a good idea.
Instead of giving ads in TH-cam, FB, blogs. U r giving something free with quality for the community and making marketing for LCO and also for code files u r mandatoryly wanted us to go. So that new people will go and buy your paid courses.
Good Idea frnd . I am not asking u for free content(as it's too much). Instead make more paid content at 199/299 , which is more useful and affordable.
Hope u reply your thoughts.

[@shahj786]

Happy independence Day Hitesh..
