TYPES OF FUNCTIONS:-
function name ( param ) {} // Normal function
var name = function (){}; //Anonymous function assigned to a variable named "name"
const name = (param) => {}; // es6 arrow function, defined with const named "name"
:)

[@aqeebhj5467]

assignment:
let sayHello = function(name){
console.log(`greeting message for ${name}` )
console.log(`Hey ${name}`)
}
sayHello('Hitesh')

[@effmerunning]

Thank you Hitesh. I am in the precourse stage of a bootcamp and their demos include 'console.log()' only, but the exercises use RETURN, which can cause students to confuse the two as producing the same result. I have watched a half-dozen videos and yours broke it down best. Subscribed.

[@asdfghjkl1770]

I know some stuffs of JS but I still following this course with 1.5x playback speed because the way Hitesh sir teach us is amazing! Keep doing this !

[@MijeshDeuja]

Really fun series to learn from. I will have already learnt JS basics before my collage courses start hahaha thanks to you.

[@yashshende2786]

Best js series 👍

He is one of the best teacher in the world , I am going to buy his online courses :)

[@delubiod1970]

I like the Indian accent. "parenthesis" is paren + thesis. Another word "parameters" is para + meters. In Brazil we have somewhat the same way of saying words, like emphasis in the last part of the word, sometimes in the middle of the word and even in the beginning of the word. Some words sounds like a roller coaster, and it sounds nice.....In English is kind of flat. like "parenthesis" but in parAmeters the upper case A is where the Americans do speak their roller coaster and Hitesh speaks like paraMeters with his roller coaster starting on M.....I love linguistics. Sorry guys, off topic, but really nice......

[@manibhushanabhishek687]

@@YoYo-eg6rc Hi I do have the same issue

[@bibhudanandadash]

Yup, It will work for few Browser and not for few as these are related to JS6 latest release, adding multiple variable in message and multi-line message. So expected that It may only work in Chrome else a browser that is upgraded to support JS6

[@Devank12]

Sir, I loved this series

[@RaviSolanki-iz9ev]

what is the difference between
Console.log(`hey ${name}`)
and
Console.log("hey" + name)
Both gives same output.
Plz explain

[@ThisIsLiving__]

you use the ${} when the value is inside a sentence for instance ..my name is ravi and i m learning JS whereas the +name u calling a defined value at the end of ur sentence for insance ....my name is : ravi you ll not be able to continue the sentence with the name in between

Awesome series sir

[@abhishekshah11]

Okay one question, why are you using back ticks in those functions when printing the function parameters?

[@rishabhkumar2264]

hii sir, i have question!! What's the difference between general function and arrow function???

[@khadijasaleem6068]

let fullName=function(num1,num2)

[@likhitachinnari4773]

Sir, what if we wanna use the parameters passed inside the function block, how to access those parameters ?

[@kartiksharma139]

*/* Really professional explanation! ^^

[@sandeepreddy830]

Only he taught us anonymous functions in this video but i hope he will also going to make a video on normal function declaration method like
function function-name()
{
}

[@umairali2360]

very informative

[@abhipadhi]

I guess statement : let sayHello = function(name){} doen't mean function's name is sayHello rather funtion is assigned to a variable named sayHello..

[@lalitgupta590]

Why you not write firstname and lastname in camel case, it is a way to write this or something else please explain it so I just clear this in my mind.

Difference bn Document.write() & console.log() ?

[@rajeshkumarverma8843]

Console.log directly shows the output in console area.
Document.write shows the output in the big screen, where the html outputs are usually shown

${ } function not working

[@SanatanaShivShorts]

♥️♥️♥️♥️♥️♥️♥️♥️

[@siddharthcharkhawala6659]

what if i write:
let name = 'john'
console.log(`Heyy ${console.log(name)}`)
its output is : Heyy undefine
BUt i don't understand why undefine.. if anyone can help me..

[@matiri91]

let name = 'john'
console.log(`Heyy ${name}`)

[@Mayankyadavmy]

because in console.log(`Heyy ${console.log(name)}`) first console.log(name) will operate which will give john and again console.log(`Hey ${john}`) will operate and john is not defined because ${Here it takes a variable}.
Hope it's clear
Tip: start operating the code from right to left and acknowledge which code will operate first.

[@jetspray3]

Dude i think most of the time that format is used as a placeholder for a variable that has been declared and assigned a value.
