Utilizing automated and specially designed codes for testing is known as continuous integration. The developers can easily deploy codes during production thanks to this process. This process is used frequently throughout the day by web developers to integrate codes. These codes are automatically checked. Errors can be found more easily and quickly thanks to continuous integration.
4. Multi-threading: What is it?
The process of multi-threading enhances CPU performance. In general, it refers to a program’s capacity to handle multiple requests from the same user simultaneously or to be managed by multiple users at once.

6. What is Long Polling?
In place of pushing data from the server to the client, long polling is a web development pattern. The client makes information requests to the server using the long polling pattern. Instead of sending an empty resource if the server has no information about the client, the server will hold the request and wait for information to become available.
7. What is Callback Hell?
There are times when you have many asynchronous functions, which is called callback hell. With so many callback functions nested in so many layers, it could become quite confusing because those functions depend on one another. The use of callback functions results in code that is challenging to read, maintain, and has the appearance of a pyramid.
8. What is CI (Continuous Integration)?
The process of frequent integrating and automating code changes into a single software project, is known as continuous integration, or CI. This DevOps technique aims to make it possible for developers to merge their code changes into a single repository for automated tests and builds. Before integration, the new code is checked for correctness using automated tools.The core of the CI process is a source code version control system. Additional checks, such as automated tests for the quality of the code and tools for reviewing the syntax and style, are added to the version control system.
