BLOCK SCOPE & Shadowing in JS 🔥| Namaste JavaScript 🙏 Ep. 9

[@programmed509]

Even the creator of javascript couldn't have made me understand this concept like the way you did brother... Just amazing!

[@jagrutsharma9150]

Things learned: 1. Code inside curly bracket is called block. 2. Multiple statements are grouped inside a block so it can be written where JS expects single statements like in if, else, loop, function etc. 3. Block values are stored inside separate memory than global. They are stored in block. (the reason let and const are called block scope) 4. Shadowing of variables using var, let and const. 5. The shadow should not cross the scope of original otherwise it will give error. 6. shadowing let with var is illegal shadowing and gives error. 7. var value is stored in nearest outer function or global scope and hence can be accessed outside block as well whereas same is not the case with let and const.

[@laxmanshrivas1500]

Great dude you gave me new idea

[@abdullahsoomro6238]

In point number 2 I want to add something. If function is defined using the "function" keyword, then "{}" are a part of its syntax. If we miss that we will get error. But in case of arrow functions, it is fine when we have just one statement in it, we can opt out "{}".

[@koreanrhythm8248]

Code inside curly brackets is stored in separate memory space called block for let and const hence they are called block s

[@swastiksharma2738]

we can shadow a let variable with var only if we are declaring it in a function as explained by ​ @abdullahsoomro6238 { } is part of function's syntax. for ex: let a = 10; function func(){ var a = 20; } this wouldn't give any error

[@AlgoSlayer]

Beautifully summarized.

[@sakshirathi3077]

Key Learnings Block is also known as Compound statements. It is used to combine the multiple statements together let & const are hoisted in a block scope. var is in global scope let and const variables are stored in block space, so it is called block-scoped but var variables can be accessed outside the block as it is stored in the Global object memory space, hence it is called Global scoped. Variable shadowing occurs when a variable declared in an inner scope has the same name as a variable in an outer scope, effectively hiding the outer variable within that scope. Example 1: let x = 10; // Outer scope variable function example() { let x = 20; // Inner scope variable, shadows outer 'x' console.log(x); // Prints 20 } example(); //function call console.log(x); // Prints 10 Example 2: var a = 199; { var a = 10; } console log(a); variables declared with var are function-scoped or globally scoped, but they are not block-scoped like variables declared with let or const. So, the var a declared inside the block {} will override the outer var a declaration, and the value of a will be 10 when logged outside the block. var variable of function scoped overwrites the value of Global Scoped variable. Scope for arrow function is also same!

First Love your explanation with examples Akshay sir, videos are exact on point!!! For Revision: Q) What is block in JavaScript? > multiple js statements formed in a group enclosed in brackets and it forms a block Q) What is need of a block/Grouping? > JavaScript sometimes expect to run a single statement to run, but we need to run commands with multiple statements which is only possible by block eg. on 4:14 write a simple function: // even empty script is perfectly valid js script, what about empty brackets!! { var a = 10; let b = 20; const c =30; } When a js script get hoisted (a Global Execution Context) gets created 'var' listed towards 'Global environment' and other variables 'let' and 'const' declarations go to the 'Block environment' This become especially important when deciding the scope of a particular variable, since b and c are located in 'Block environment' and for a as we know exists in 'Global environment' any statement out of the "Block" can access 'a' ie. ' Variable in Global environment' and other are not! so when we understand the extent of Global and local environment variables and their 'Scopes' == Environment that forms the lexical hierarchy of 'Scopes' and 'Scopes' have Levels like 'Scope inside scope' see script in 7:03 var a = 100; { var a = 10; let b = 20; const c =30; console.log(a); console.log(b); console.log(c); } console.log(a); console.log(b); console.log(c); So in block " var a = 10;" influences the value within the block hence console.log(a); >> 10 and outside of the block 'Variable in Global environment' influences value of a hence console.log(a); >> 100 Illegal shadowing: let a = 200; { var a =20; } as 'var' declaration goes to 'Global environment' and sets in Memory context, it cannot be set using 'Block environment' value Hence: Uncaught SyntaxError: Identifier 'a' has already been declared

[@dgdivyanshugupta]

Here a question then : var a=100; { console.log(a) var a=10 } What would be the expected value of this program according to the concepts explained? Since we say the block influences the variable, then will we get undefined(due to variable being referred before it was declared in the lexical scope) or will we get 100?

[@surajpatil3247]

thanks brother

[@0xFOXHOUND]

​@@dgdivyanshugupta first var a=100 affect the inner scope value (consider it as a onion) as outer exec context is covering inner exec. context so sorry for super late reply

[@RM-lb7xw]

@@dgdivyanshugupta var doesn't follow block scope so your code is basically the same as var a = 100; console.log(a); var a = 10; So the code will log the value 100. Now lets say we had let or const instead of var in your code. So the code becomes: let a = 100; { console.log(a); let a = 10; } Since let and const follow block scope, the above code will throw a ReferenceError saying it cannot access 'a' before its initialized. The best way to understand this is by looking at those brackets {}. SInce a is being logged on to the console before its initialized in the {}, it throws an error. Thats what block scope's all about.

[@mahabaskaran6359]

I have a question on illegal shadowing. let a = 200; { var a =20; } `let` goes to different memory called "script" and var goes to "Global". Why is it mentioned as crossing boundaries in the video. Can someone please explain me this.

[@mayureshkakade3241]

Are functions block scoped? When I declare a function inside a block, then I could see it in global scope as undefined hoisted. When execution enters inside the block, then the function is seen in the Block scope as well as global scope? Is this some other concept?

[@rohitbisht5457]

Thank you sir for making these videos. After watching your video i played with my program to see How it handle everything behind the scene and after sometime i found some interesting things that when u use type="module" in your script tag the js engine will put all the variables and func. and class in module scope also when we put a function in block it behave differently . Sir can you make a video On this topic ? Thank you very much and stay healthy

[@momentswithmanisha]

Block :- It is used to combine multiple statement into one statement so that we can use it at those places where javascript expects to have single statement. Scope :- scope of a variable or a function is the place where these are accessible. Block scope :- The variables and function present within the scope of a block section. And block follows the lexical scope chain pattern while accessing the variable. Shadowing :- Providing same name to the variable as of those variable which are present in outer scope. Thanks Akshay for clearing the concept so nicely.🙏

If you didn'nt understood illegal shadowing read this....... illegal Shadowing : var is not scoped to the block it's in, it's scoped to the containing function. If there is no containing function, it ends up in the global scope. Hence it conflicts with the let a declaration which is conflicting during code component phase

Watched it again and again, practices it, now finally i'm clear with block, block scope, shadowing, illegal shadowing, Thank you Akshay Saini it was helpful.

[@kirtikhohal5025]

Here is the full notes of the video: 1. Block : { }, this is a perfect example of a block. Block is also known as Compound Statement. Block is used to combine multiple JS statements into one group. 2. Block scope means what all variables and functions we can access inside the block. 3. Eg : { var a = 10; let b = 20; const c = 30; } 'a' is hoisted in the global memory space, whereas let and const i.e., 'b' and 'c' are hoisted in some other memory space which is known as "Block". And that's why we say let and const are block scoped. When JS engine finishes executing this block, 'b' and 'c' will be no longer accessible outside this block. But you can access 'a' outside of this block, because 'a' is globally scoped. 4. Eg : var a = 100; { var a = 10; console.log(a); } Output : 10 Here, local variable 'a' shadows the global one in that block, that's why the value of 'a' in the block is 10 and not 100. Moreover, the value of 'a' is altogether changed to 10, and that's why if you'll try logging 'a' outside this block, you'll get its value as 10. This happened because both the 'a' are pointing towards the same memory location, which is there in the global scope. But, this is not in the case of let and const declarations, local let declaration cannot shadow the global let declaration, in a block. Eg : let a =1; { let a = 10; } The local 'a' here cannot shadow the global 'a' here, because the scopes in which these 'a' are falling are different, and hence the memory locations of both these variables will be different, local 'a' is stored in Block while global 'a' is stored in global memory space. Hence, the manipulation in one cannot affect the other. Similar type of behavior is also expected in case of const declarations. Shadowing works the same way in case of functions as well, since we can assume functions as a block only. 5. Illegal Shadowing : Eg : - let a = 10; { var a = 20; } This is an example of illegal shadowing, you cannot shadow a let variable using a var declaration in a block. You can shadow a let declaration using a let, but not var. Because, in the same scope, let cannot be re-declared. But, we can shadow like this : let a = 10; { let a = 20; } Because, here 'a' has different scopes, one is block and one is global scope, so re-declaration can be done here. 6. Lexical block scope with code example : Eg : - let a = 10; { { console.log(a); } } In the above example, the variable 'a' is declared in the global scope, but this 'a' can be accessed inside any block or any inner block. Firstly, the JS engine tries searching for 'a' in the current block it is executing, if it does not find there, it searches 'a' in the immediate ancestral lexical environment, and if still does not find there too, it expands it search to higher ancestral lexical scopes, it finds 'a' in the global scope, took its value, and printed on the console.

[@ravinamohite07]

thank you 👍

[@poorvashukla]

loved the video ... understood the difference between block and scope, block is used to write multiple statements where javascript would expect one statement; whereas scope defines the variables and functions that we can access from the part of code

[@travelingDeveloper]

Block is set of statements in JS where Js expects a single statement. Lexical scope (Local memory + Reference to Lexical enviroment of its parent) works same inside the block also. let and const are block scoped and they would reside in a separate memory called block unlike var which has global scope. Shadowing is basically overriding of the variable. Illegal shadowing:- Shadowing of let to var and it will throw syntax error.

Nice videos Akshay! I have one doubt, If let creates a different scope for 'a', then why can't we shadow it using var, it will be a different scope, right?

[@rhythm1723]

hey i have same doubt ... did you get answer

[@_sunsetstories_]

@@rhythm1723 not yet

[@shubhamsingh-cd7iv]

I think because var has scope outside the block as well. So when control exits the block and comes into global scope, var a comes into direct conflict with let a. This is a case of redeclaration which let doesn't allow. That is why, we can shadow let a by function-scoping the var a.

[@Divya-h5w]

Because var is not block scoped. It is global scoped and functional scoped where as let and const are block scoped and functional scoped. So var inside block scope is allocated in global memory and then we have let variable so we get error as it already exists.
