Sir we request you to make one long video like this about ES6 ,that covers everything about ES6,,,,,plzz

Things learned: 1. What is Function Statement ? A. A normal function that we create using Naming convention. & By this we can do the Hoisting. For Ex - function xyz(){ console.log("Function Statement"); } 2. What is Function Expression ? A. When we assign a function into a variable that is Function Expression. & We can not do Hoisting by this becz it acts like variable. For Ex - var a = function(){ console.log("Function Expression"); } 3. What is Anonymous Function ? A. A Function without the name is known as Anonymous Function. & It is used in a place where function are treated as value. For Ex - function(){ } 4. What is Named Function Expression ? A. A function with a name is known as Named Function Expression. For Ex - var a = function xyx(){ console.log("Names Function Expression"); } 5. Difference b/w Parameters and Arguments ? A. When we creating a function & put some variabels in this ( ) that is our Parameters. For Ex - function ab( param1, param2 ){ console.log(" } & When we call this function & pass a variabel in this ( ) that is our Arguments For Ex - ab( 4, 5 ); 6. What is First Class Function Or First class citizens? A. The Ability of use function as value, * Can be passed as an Argument, * Can be executed inside a closured function & * Can be taken as return form. For Ex - var b = function(param){ return function xyz(){ console.log(" F C F "); } } 7. Function are heart of JS. They are called first class citizens or first class functions because they have the ability to be stored in the variables, passed as parameters and arguments. They can also be returned in the function.

[@maneesharandeniya]

"When we assign a function into a variable that is Function Expression. & We can not do Hoisting by this becz it acts like variable." Cannot do hoisting is wrong here. Variable is hoisted. It means It cannot execute as function until it is defined as function.

Thanks😍

[@biswaranjanbarik4052]

thanx man.

[@sanamahuja2033]

Stmt vs expression. Expr can involves operand and operations. And expression can be assigned a value or executed as a value stmt cause side effect. Fn stmt is same a declaration without assigning it to a var eg. Function a Expr- var a = fn Anonymous without name iife or assignment First class citizens Named fn expr When fn with a name is assigned to a variable also this name is local scoped it can be used for recursion but not outside Arrow fn you know context is same parent

[@suman-majhi]

akshay bhaiya confused in interview. My ans would be at that point: Every function is beautiful, either it is function expression or it is function statement. 😂😂 love you bhaiya❤️❤️

[@0xFOXHOUND]

The interview startup's name rhymes with "Tomato" For Revision Function statement / Function Declaration : the function is normally defined and can be used later on Function expression : the function is first created and assigned to a variable so that it can be called by its variable name and unless it is defined, it cannot be executed otherwise it throws out "Uncaught TypeError" Anonymous function : function where there is no need to define name for the function, it just can be assigned to variable Named function : Normal function with its name assigned to a variable !!In this case you cannot call function by its name in outer scope!! (Scope Chain) first class Functions / first class citizens : 1) used as values 2) can be passed as argument 3) can be executed inside a closured function 4) can be taken as return

[@akshaysharma30498]

You are the type of guy I can sit and have long conversations with, without getting bored. I like learning new stuff and going to my workplace and tell others about it, unfortunately "That's so cool" isn't the reaction that you get from most people because knowledge doesn't make people go "That's so cool" usually. But it does to me and I assume you'd react the same way too XD I have a workplace senior I hang around with for most of the free time coz we both fall in this category. Thanks for all the videos. I must admit tho I'm jealous coz I like explaining stuff with same enthusiasm as you but ... nobody would listen to me and then it just feels like it doesn't matter that I know it :/

First video of yours, I watched on KZbin was "async vs defer attributes in Javascript" almost 1.5 year back. I watched it so many times, almost before every interview and I commented first time on KZbin because that explanation compelled me to write something in comment and I wrote "I usually don't comment on YT but you compelled me to do so" and I got a reply from Akshay sir/Akshay bhai/Ustaad ... from that day only, I am addicted to write these long comments and I usually got reply from Akshay bhai. Thank you so much. We (the student of yours) will always remember you. You will be remembered for you great work forever. Love

[@SakibulIslam--]

1. An anonymous function is a function that does not have a name. we can not declare an anonymous function. it,s gives a syntax error. if we store anonymous function in a variable, it,s known as a function expression. we use anonymous function only as a value. 2. One common use case for anonymous functions is as callback functions, which are functions that are passed as arguments to other functions. 3. In JavaScript, functions are considered to be first-class citizens. just because of 1 . we can use Functions as values. 2. we can use Functions as arguments 3. we can use Functions as return values 4. difference between a function statement or declaration with a function expression and an arrow function is hoisting.

Remember points 1.Function declaration or statement? a.funtion with keyword function and name is called function declaration or statement 2.function expression? a. When function is declared with a variable is called function expression for ex like this var a= function (){} So the main difference between expression and declaration is in the concept of hoisting we can't call the expression function before initialisation 3.anonymous function? a. Function without a name is called anonymous function when we try to call the function it is give error ex function (){} 4.first class functions? The function is used as a value and used as a argument in other functions, and return the functions inside other functions together is called first-class functions or first class citizens

[@Saikrishna-mw5ti]

In JavaScript, functions are a fundamental building block of the language. Here are brief explanations of some important concepts related to functions in JavaScript: Function Statement: A function statement is used to declare a named function. It uses the function keyword followed by the function name, a list of parameters (in parentheses), and the function body (in curly braces). Example: javascript function greet(name) { console.log(`Hello, ${name}!`); } Function Expression: A function expression is used to create a function value and assign it to a variable or a property of an object. It can be either anonymous or named. Example: javascript const greet = function(name) { console.log(`Hello, ${name}!`); } Function Declaration: A function declaration is a statement that declares a named function in the current scope. It is similar to a function statement, but can be used inside any block, not just at the top level. Example: javascript if (someCondition) { function greet(name) { console.log(`Hello, ${name}!`); } } else { function greet(name) { console.log(`Hi, ${name}!`); } } Anonymous Function: An anonymous function is a function without a name. It can be defined using a function expression or passed as an argument to another function. Example: javascript setTimeout(function() { console.log("Time's up!"); }, 5000); Named Function Expression: A named function expression is a function expression with a name. The name can be used to refer to the function inside the function body or from outside. Example: javascript const greet = function sayHello(name) { console.log(`Hello, ${name}!`); } greet("Alice"); // "Hello, Alice!" sayHello("Bob"); // ReferenceError: sayHello is not defined Parameters and Arguments: Parameters are the named variables that are defined as part of a function declaration or expression. Arguments are the values that are passed to a function when it is called. Example: sql function sum(a, b) { return a + b; } const result = sum(2, 3); // arguments: 2, 3; parameter names: a, b console.log(result); // 5 First-Class Functions: In JavaScript, functions are first-class citizens, which means they can be treated like any other value. They can be assigned to variables, passed as arguments, and returned from functions. Example: javascript function sayHello(name) { console.log(`Hello, ${name}!`); } const greeting = sayHello; // assigning a function to a variable greeting("Alice"); // "Hello, Alice!" Arrow Functions: Arrow functions are a shorthand syntax for defining functions. They use the => symbol to separate the parameter list from the function body, and can have an implicit return value if the body is a single expression. Example: javascript const greet = (name) => { console.log(`Hello, ${name}!`); }; const double = (x) => x * 2; // implicit return value

[@vitalvisions4U]

I'll remembere this for lifetime - first class functions have ability to use function as values to pass it to another function or to return it from a function.
