Sir i can't see the next videos they are showing private videos. Plz help sir

@pranshuaggarwal 3 года назад

Yes sir. I remember, 2 years back i started with your Javascript playlist and that made me feel afraid of this language after i watched your arrow functions video. Since that was terrible and made me feel afraid of this language. But now i thought I should give this language one more try and I can't believe, you made this new playlist so easy to understand. Each and every concept is explained so good, even a layman can understand it, I am just a programmer. Thankyou for making this online Javascript course freely available to us.

Oo boi this nasty arrow function and callback function settle everywhere on the code!! Warning the most important topic of js

@akshaysavad7350 4 года назад

Not concerned with video subject.. But Indian intern need to make some app or website from scratch and in return they only get intership certificate (that if their bosses are good else forgot that also). Is this injustice ?

@VijayKumar-eq9ou 4 года назад

Sir pls continue this series , it's very explanatory and useful for everyone

@raghavgupta6186 4 года назад

Sir it is like lambda or anonymous function in Python , I understood it easily

@shahzadisairaawan5079 3 года назад

finally understood the callback function. thank you so much sir

@MaheshKumar-qx8dy 4 года назад

Best video to understand arrow function and return keyword. Thanks a lot Hitest, you made my day ;)

@somagorai8159 2 года назад

At 6:23, you wrote isEven and not isEven() and you gave the reason that we are passing by reference. Can you please explain that, thanks!

@ritish181 Год назад

Hey... Firstly thank you sooo much for the course @Hitesh Sir. Its really confusing 😵 sometimes , don't know if java script is tough or what.

@AsanTutorials 3 года назад

let isEven = element => element % 2 === 0; console.log(isEven(2)); true

@aayush5474 4 года назад

If you have only one input parameter you can even omit its paranthesis

@afamsval 4 года назад

@umairali2360 2 года назад

is every method always return true or false???

@erranbahadurbk 3 года назад

If anyone is from c# its same as lamda expression!

@kamilmohammed9722 3 года назад

@kuzhalmalan4703 4 года назад

Good Noon Hitesh, I am following up your videos from last week and need some clarifications on below mentioned: How can we add type of operator in the below console.log using interpolation to get group of results in single query. console.log (` // Added number is : ${add} // Subracted number is : ${sub} // Multiply number is : ${mul} // Divided number is : ${div} // Modulus number is : ${mod} // Greater number is : ${greater} // Lesser number is : ${lesser} // Equal number is : ${equal} // `); I have tried to use typeof as below and will getting result as string alone. console.log (typeof` // Added number is : ${add} // Subracted number is : ${sub} // Multiply number is : ${mul} // Divided number is : ${div} // Modulus number is : ${mod} // Greater number is : ${greater} // Lesser number is : ${lesser} // Equal number is : ${equal} // `); and also suggest to put numbers on thumbnails for identification of classes in order. Thanks!!!

@shaqranbhat1168 4 года назад

We also dont need to put a parentheses around 'e' as there is only one argument and it's not a non-simple identifier. This makes it look much cleaner: """"""var result = [array].every(e => e%2 === 0); console.log(result);""""""""

@haythamkenway8343 4 года назад

I like this trick to check even or odd arrays: const isArrayEven = [2, 4, 6, 8].every(x => !(x & 1));

similar to python for loop..

@SahilPatel-jv1fw 3 года назад

Array.prototype.map() expects a return value from arrow function array-callback-return i am stuck at this error

@RAKESH-nf9bi 4 года назад

var result=[2,3,4,5].every(iseven) is not working in console of my browser

@programoftech9200 4 года назад

Present Sir Do you remember me?

@lukes5631 2 года назад

I cannot express, as a new coder, how informative it is to have a complete tutorial like this. The way you progress through the knowledge with your explanations and mid-way recaps it brilliant and also showing (in a progressive manner) how to move toward and understand the new syntax. I have actually LEARNED a lot from this one video in a way that I can take that knowledge and apply it pragmatically - not just a theoretical understanding. Thank you.

@tuanphamvan655 3 года назад

thank you great video I understand more about callback

@ahmeddirie4860 2 года назад

thanks.

@jagpreetsingh8288 4 года назад

One question- Why we are using callback if we are already getting the same result from IsEven Function? why we are using callback in var result?

@vijaynavale3919 4 года назад

Is actually there different scenarios we have to use callbacks in here for example when he applied every() method the isEven function get call only when every() method pass numbers as isEven element parameter then after passing function get triggers. You will see this type of scenarios in dom manipulation.where use click or submit the form then that event triggers the callBack function Remember callback is simply mean call the function later

Your IDE And the Theme please...

@alltech-jg9hi 4 года назад

had to spend 2 days on this but i understand it now thanks,

@theboxdev 4 года назад

Why we are not Putting () in isEven like isEven()? However thanks for awesome tutorials

@vijaynavale3919 4 года назад

Is because we are passing isEven as call back so we can call it later if you pass like this isEven() then Javascript will immediately call this function we don't want like this. Again you will see this in DOM manipulation where use click and then only function runs. Hope you understood

@gajjalaharsha 4 года назад

Sir, is it necessary to have semicolon (;) at end of arrow function other wise will it give syntax error?

@SharukhKhan-sd7xg 4 года назад

semicolon (;) are not compulsory in JS if you forgot to use ; then it will not throw an error.
