1.JS creates Global excution context 2.Next it creates memory phase 3.Memory phase - In this phase,the variables are set to undefined until the execution phase(next phase) and the functions are set to their definitions. 4.Next it creates the execution phase 5.Execution phase - In this phase,the variables are initialsed to given values and when the function s are called,it creates a memory phase and execution phase for the function just like the main one. For live demo: browser > inspect > Sources create a snippet with few functions and visually experience the call stack. correct me if there are any mistakes or add to this if something is missing.

[@keshav1955]

Returned value is passed to the global environment

[@sumitbhardwaz]

Execution context gets deleted as well

[@shubhamtyagi2901]

If you can elaborate a little more on the demo part, like how to do things over there on browser, anyways u've done a good job 👍my friend

[@AnujJainCSIT_32]

Understand call stack with the help of live demo : browser > inspect > Sources 1.then create a snippet by clicking on the arrow(>>) next to workspace 2.then write down some functions in the created snippet ,do save them by ctrl+S 3.Create breakpoints and run the code and keep eye on call stack to visualize how it works. correct me if there are any mistakes or add to this if something is missing.

can anyone explain factorail program using recursion ? `function factorial(n) { if (n === 0 || n === 1) { return 1; } return n * factorial(n - 1); } // Example usage: console.log(factorial(5)); // Output: 120`

I am having two years experience as a front-end developer but the things cleared here that was no one explain. Even not talked about, so thanks a lot for your way of teaching. 👏👏

[@harshalkhobragade972]

🔵The working of the JavaScript works on three phases: 1. Global Execution Context 2. Memory phase / Creation phase 3. Execution phase 🔵Phase 1: Global Execution Context The value of `this` keyword is set to Global Execution Context (which is an empty Object in NODE environment, & window object in browser environment) 🔵Phase 2: Memory phase During this phase, JS engine scans the code and assigns the initial values for the variables , functions, etc.. For variables they are 'undefined' and for functions they are set to their function definition 🔵Phase 3: Execution phase After the creation phase completed, the execution phase begins where actual values of the variables are set. And when the functions are called it creates a new 'Function Execution' context which consists of two phases (they works same as explained above but only for the particular function scope): 1. Memory phase 2. Execution phase 📝The return value of the 'Function Execution' context is passed to the Global Execution Context Amazing videos Hitesh Sir, Learning a lot..!! 🔴Correct me if something I explained is Wrong

[@salmanhaider8182]

ap na corse complete kar lia ha?

[@mansoorafzal4344]

Honestly, no one has every explained like this before. u really deserve appreciation....

[@nitinmore7686]

Seen first time how program runs in memory! Thnx Hitesh ji! I was waiting for this to understand since 2011...!

[@nitishsingh925]

very good understanding 💯 with chai aur code thank thanks mr. hitesh choudhary sir .......... There are three types of execution contexts in JavaScript: Global execution context: This is the default execution context that is created when the code is executed in a global scope. Function execution context: This is the execution context that is created when a function is called. Eval execution context: This is the execution context that is created when the eval() function is called

[@Yuvraj-Singh577]

Global Execution Context contains two phases 1. memory component 2. code execution component --- In memory component memory is reserved for variables(initially assinged with undefined) and functions(assigned with defination) whereas in code execution component all assignment of variables, calculations etc. are performed.

brilliant video, no one explains such complex topics with such ease, LEGENDARY

Sir this video was much needed. Coding toh theek hai practice se aa jaati hai lekin yeh in depth baatein aage interviews mein kaafi acha impression bana ti hai. This is a good and in depth video

[@music_2311]

Amazing video i never seen a educator who teach and talked about any language & in its components in this depth.... Thanku for this and please post more videos like this ...

[@Freak_15]

Ek saal se jyada hone ke baad iss video ko dekh raha hu. Pr quality last year se abhi tak mei kahin nahi mili aisi. Isse clearly pata chalta hai ki @chaiaurcode kaafi teachers se 1 saal pehle hi itna cover karke bethe the. Thanks for the work sir. We'll appriciate your work and yes, things will come up. Let's see

[@HetalSheladiya-l7d]

Very depth explanation after 4 years of working today I understand how JavaScript exactly works... Thanks Hitesh sir...i have seen many other videos but not understood

[@sindhurapogarthi5844]

Thank you so much for such clear explaination of Global context execution,functional context execution and call stack. This video is very helpful.

[@chaiaurcode]

Glad it was helpful!

[@ramansworld3879]

hatsoff to you.... I landed to watch your react video , but in react video you said, dont watch it if you dont know javascript.... That was turning point for , coz I never heard a youtuber says, dont watch this if you you dont know that first.... In fact I bought a code on udemy for react , but couldn't complete as the person used all advance concept of JS, but in the begining he said , you can learn react even ifyou are naive to JS...Believe me I couldn't complete... its still there... BIG SALUTE TO YOUR TEACHING STYLE.... WORLD IS RUNNING COZ OF GIVERS LIKE YOU :)

One of the Greatest Teacher I ever come across.Hands Down

[@saadmushtaq926]

I'm 24 years old now, and up until today, I have never subscribed to anyone on KZbin. You're the first and only one I've subscribed to! Thanks so much for the JavaScript tutorials-they've been incredibly helpful. What I love the most is how you explain everything so slowly and clearly. It makes learning so much easier. Your teaching style is truly one of a kind! 🤍

[@LegendXo_OP]

one of the best video of an entire js series I have watched!!!!!! I love it

[@govindsen2230]

IMP DOUBT: I think variable declared with "let" should be replaced by "var", because on adding breakpoints and running on browser, var is giving "undefined (that is in Global scope)" and let is giving "value unavailable (that is in Script scope)". Reason behind this is "var" can be accessed before its execution and gives value as "undefiend", whereas "let" and "const" gives error that "they cannot be accessed before initialization"". REASON: Because of Temporal Dead Zone.

[@karanveerseniarey]

I also have the same doubt.

[@codenoobdev]

whenever i see sir's video notification it makes me feel so good. Even though I know the basics but still i watch it because itna deep teaching koi nai karta.. thanks

[@SandeepDhama]

Ye concept maine kahin padha nahi tha. Main ek Google Apps Script ke andar ek project bana raha tha to wahan debugging karte time se notice kiya tha. Abhi aur bhi clear ho gaya.

i'm frontend and backend developer , working on js and jquery from last 2-3 year i just seen your react videos which is very intertesting so i want to see to js playlist , but the concept i see , i was not learned in my whole career because in the playlist you execute the code in every senrio ether its a error or not . I loved it so much and it clear many concept truly appricated. I shared your channel to my collegue and my known IT student as well

[@nitinparmar8101]

Hey Programmers!! if you are not able to understand this concept then don't worry, it is very ease for understanding this you should have knowledge of DS, I am CS student, when I learn DS for my unvirility exam that time I was thinking why I learn this , but now I understand importance of DS, in this video Hitesh Sir talking about Stack Data structure, if you want to learn this in very ease way then I prefer "Jenny's Lectures CS IT", check their DS playlist , in market their are many DS course but I learn form them and I understood most of all concept. Good Luck👍

After watch this video my all doubt are clear in call stack.

[@wisdombro316]

16:28 Remember guys, That does not happen immediately, first, the code is executed within its execution context, and it is retained in the call stack, when the function completes the execution context is popped off the stack.

I know some people don't understand what sir is explain.... he is not tell how it is connected.... suddenly execution context and suddenly call stack how it came... many people have this doubt..... I already know this concept so i know what he is explaining..... if you are not understanding then i recommend you to ones go through the namaste javascript Playlist.... maybe in first time you won't get the concept ... then watch it 2 to 3 times you will definitely get it....
