Virtual DOM is a lightweight copy of the actual DOM in memory, used for efficient updates and rendering in web development.
Virtual DOM is a concept used in frameworks like React to improve performance by minimizing actual DOM manipulations.
When changes are made to the virtual DOM, a diffing algorithm compares it with the actual DOM and only updates the necessary parts.
This helps in reducing the number of updates needed...
Event loop in JavaScript manages asynchronous operations by executing callback functions in a queue.
Event loop is responsible for handling asynchronous operations in JavaScript.
It continuously checks the call stack for any pending tasks and executes them in order.
Event loop ensures that the code runs efficiently without blocking the main thread.
Example: setTimeout function in JavaScript uses the event loop to execute a
Prototypes in JavaScript are used to add new properties or methods to existing objects.
Prototypes allow for inheritance in JavaScript.
All objects in JavaScript are linked to a prototype object.
Modifying the prototype object affects all instances of that object type.

Redis is single-threaded.
Redis is single-threaded, meaning it can only execute one command at a time.
This design choice allows Redis to be extremely fast and efficient for certain use cases.
However, it also means that Redis may not be the best choice for highly concurrent workloads.
Data types that can be used as keys in Python include strings, integers, floats, tuples, and custom objects.
Strings are commonly used as keys in Python dictionaries.
Integers and floats can also be used as keys.
Tuples can be used as keys if they only contain immutable elements.
Custom objects can be used as keys if they are hashable.
Examples: {'name': 'John'}, {1: 'apple'}, {(1, 2): 'tuple'}
Types of indexing in SQL include clustered, non-clustered, unique, and composite indexes.
Clustered index physically reorders the table based on the index key
Non-clustered index creates a separate structure for the index
Unique index ensures that all values in the index column are unique
Composite index uses multiple columns for indexing
