Q2. Difference between async await and promises
Ans. 
Async await is syntactic sugar for promises, making asynchronous code easier to read and write.
• Async await allows writing asynchronous code that looks synchronous, making it easier to understand.

• Promises are objects that represent the eventual completion or failure of an asynchronous operation.

• Async await is built on top of promises and provides a more concise and readable way to work with asynchronous code.

• Async funct...read more

Q3. Explain Callback hell
Ans. 
Callback hell is a situation in asynchronous programming where multiple nested callbacks make the code difficult to read and maintain.
• Occurs when multiple asynchronous operations are nested within each other

Q1. Different between shallow copy and deep copy.
Ans. 
Shallow copy only copies the references of objects, while deep copy creates new copies of objects.
• Shallow copy creates a new object but does not create copies of nested objects.

• Deep copy creates new copies of all nested objects.

• Shallow copy is faster and more memory efficient, but changes to nested objects affect both copies.

• Deep copy is slower and uses more memory, but changes to nested objects do not affect the origi

Q2. Generator in python.
Ans. 
Generators in Python are functions that allow you to iterate over a sequence of items without storing them in memory.
• Generators are created using the 'yield' keyword instead of 'return'.

• They are used to generate a series of values on the fly, one at a time.

• Generators are memory efficient as they do not store all values in memory at once.

• Example: def my_generator(): for i in range(5): yield i

• Example: for num in my_ge
