Q17. Explain the difference between REST and GraphQL
Ans – The main and most important difference between REST and GraphQL is that GraphQL does not deal with dedicated resources. Instead, everything is considered as a graph and therefore is connected and can be queried to app exact needs.
Ans – Node.js is a single-threaded application but it supports concurrency via the concept of event and callbacks. As every API of Node js is asynchronous and is a single thread, it uses async function calls to maintain the concurrency. Node uses an observer pattern.
Node thread keeps an event loop and whenever any task gets completed, it fires the corresponding event which signals the event listener function to get executed.
11. How is GraphQL different from REST?
This is typically a difficult question to answer, but a good developer will be able to go through this with ease. The core difference is GraphQL doesnt deal with dedicated resources. The description of a particular resource is not coupled to the way you retrieve it. Everything referred to as a graph is connected and can be queried to application needs.

10. What is multithreading and how it is used?
The main purpose of multithreading is to provide multiple threads of execution concurrently for maximum utilization of the CPU. It allows multiple threads to exist within the context of a process such that they execute individually but share their process resources.
9. What is Continuous Integration?
Continuous Integration (CI) is a practice where developers integrate code into a shared repository regularly to detect problems early. CI process involves automatic tools that state new codes correctness before integration. Automated builds and tests verify every check-in.
Q23. What are the disadvantages of GraphQL?
Ans – Disadvantages of GraphQL are:
