    - Then, it will throw an error: `TypeError: Assignment to constant variable`.
    - The constant `chaiCode` is declared using `const` and assigned the value `"ChaiCode.com"`. Attempting to reassign it results in an error since constants cannot be reassigned.

-   ## Feature Request 1
-
-   **Code:**
-   ```jsx live
-   let number1 = 10;
-   let string1 = "hello World";
-   let boolean1 = true;
-   let object1 = {
-       name: "Chai",
-       key: "code"
-   };
-   let array1 = ['Fruits', 'Chai', 'Vegetable'];
-
-   console.log(`${number1} is a  ${typeof number1}`);
-   console.log(`${string1} is a  ${typeof string1}`);
-   console.log(`${boolean1} is a  ${typeof boolean1}`);
-   console.log(`${object1} is a  ${typeof object1}`);
-   console.log(`${array1} is a  ${typeof array1}`);
-   ```
-
-   **Outcome:**
-   - The console will display:
-     ```
-     10 is a  number
-     hello World is a  string
-     true is a  boolean
-     [object Object] is a  object
-     Fruits,Chai,Vegetable is a  object
-     ```
-   - This shows the type of each variable using template literals and `typeof`.

-   ## Feature Request 2
-
-   **Code:**
-   ```jsx live
-   let hello = "world";
-   console.log(hello);
-   hello = "Hello Chai";
-
-   const HiteshSir = 'Chai Aur Code';
-   console.log(HiteshSir);
-   HiteshSir = 'www.chaicode.com'; // This line will cause an error
-   ```
-
-   **Outcome:**
-   - The console will display:
-     ```
-     world
-     Hello Chai
-     Chai Aur Code
-     ```
-   - Then, it will throw an error: `TypeError: Assignment to constant variable`.
-   - The variable `hello` is declared using `let`, initially assigned the value `"world"`, and then reassigned the value `"Hello Chai"`.
-   - The constant `HiteshSir` is declared using `const` and assigned the value `'Chai Aur Code'`. Attempting to reassign it results in an error since constants cannot be reassigned.

-
-   **Summary of Key Learnings:**
-
-   1. **Variable Declarations:**
-      - `var` declares variables with function scope or globally if declared outside a function.
-      - `let` declares variables with block scope, allowing reassignment.
-      - `const` declares variables with block scope, but they cannot be reassigned after the initial assignment.
-
-   2. **Type Checking:**
-      - The `typeof` operator is used to determine the type of a variable.
-
-   3. **Reassignment:**
-      - Variables declared with `let` can be reassigned.
-      - Constants declared with `const` cannot be reassigned, and attempting to do so results in an error.
-
-   4. **Template Literals:**
-      - Template literals (using backticks) allow embedding expressions within strings using `${expression}`.
