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.

A trigger is a special type of stored procedure that automatically executes when certain events occur in a database.
Triggers are used to enforce business rules, maintain data integrity, and automate repetitive tasks.
They can be triggered by INSERT, UPDATE, or DELETE operations on a table.
Examples of triggers include auditing changes to a table, updating related tables when a record is modified, or enforcing referential
Clustered indexes physically order the data in the table, while non-clustered indexes do not.
Clustered indexes determine the physical order of data in the table, while non-clustered indexes do not.
A table can have only one clustered index, but multiple non-clustered indexes.
Clustered indexes are faster for retrieval of data, especially range queries, compared to non-clustered indexes.
Non-clustered indexes are stored se...

Questions on Java basics - .equals() vs ==, Fibonacci series, and MultiThreading.
The .equals() function compares the values of two objects, while == compares their memory addresses.
Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.
MultiThreading is a technique where multiple threads of execution run concurrently within a single program.
Examples: 5 == 5 is true, but new Str...
