Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their scope.
Hoisting applies to variable and function declarations, but not to variable assignments

ES6 added several new features to JavaScript including arrow functions, let and const, and template literals.
Arrow functions provide a more concise syntax for writing functions.
Let and const are block-scoped variables that replace var.
Template literals allow for easier string interpolation and multiline strings.
Other features include destructuring, default parameters, and classes.
Lexical scope in JS determines the accessibility of variables based on their location in the code.
Variables declared inside a function are only accessible within that function's scope
Variables declared outside of any function have global scope
Nested functions have access to variables declared in their parent function's scope
Lexical scope is determined at compile time, not runtime

OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPS focuses on creating objects that interact with each other to solve complex problems
Key principles include encapsulation, inheritance, polymorphism, and abstraction
Encapsulation ensures that the internal state of an object is hidden from the outside world
Inheritance allows a class to inherit...

To implement a queue using a stack, use two stacks and simulate the queue operations.
Use two stacks, one for enqueue operation and one for dequeue operation.
For enqueue operation, simply push elements onto the stack used for enqueueing.
For dequeue operation, if the dequeue stack is empty, pop all elements from enqueue stack and push onto dequeue stack.
Then pop from the dequeue stack to simulate dequeue operation.
