    Lecture # 1:
    Variables and Data Types
    const = can't be re-assigned a value and can't be declared again (block scope)
    let = can be re-assigned a value but can't be declared again (block scope)
    var = it can be re-assigned a value and it can also be declared again (Global scope)
    => Never use var in your code instead of let because of block and functional scope issues.
    # console.table([group of variables you want to show in tabular form])

    Maine VBA aur Apps Script mein bahut saare projects kiye hain. VBA mein to Simple CRM Systems tak build kiye hain. Main ek full stack developer banna chahta hoon kyunki mujhe apna kuch build karna hai. Jab koi bhi aisi jankari milti hai jo mujhe nahi pata thi bahut khushi hoti hai ki chalo ye concept to clear hua. Aapki video mein aapka experience dikhayi deta hai Sir. Kyunki kuch cheeze documentation se nahi experience se hi samajh aati hain.

    Hitesh please don't mind but there are a lot of people who start coding for the sake of coding...They don't understand enough so they get disheartened and just do their job and leave. When I was starting, I was very dumb. My first language was Java. I felt out of place but then slowly, I started to invest my time into learning the language...and so during my class 6 post exam holiday, I sat with my class 5 and class 6 books. Read every line , typed stuff on my old computer and slowly within 1 year, I got the hang of Programming. From that day, I have loved learning languages. So You can inspire by your teaching even to someone who just wants to code. We all need a good mentor else after feeling dumb for years, we just give up. So welcome everybody to your terrific teaching sessions ❣ We all need a mentor like you

    var, let, and const are all ways to declare variables in JavaScript, but they differ in scope, hoisting behavior, and mutability.
    var: It's function-scoped and hoisted, meaning it can be accessed before declaration within its function. Variables declared with var can be re-declared and re-assigned. It's now generally replaced by let and const in modern JavaScript due to its less predictable behavior.
    let: Introduced in ES6, let provides block-scoping, which confines it to the block (like loops or if-statements) where it's declared. It's not accessible before its declaration due to the Temporal Dead Zone. let allows re-assignment but not re-declaration in the same scope.
    const: Also block-scoped and subject to the Temporal Dead Zone. It must be initialized upon declaration and cannot be re-assigned or re-declared. It's ideal for declaring constants whose values should remain unchanged throughout the execution.
    In summary, prefer let and const for their block-level scoping, which enhances code readability and maintainability.
    Use let for variables that change and const for variables that should remain constant.
