Crawlers receive a full-rendered HTML response, which is far more SEO friendly rather than a single page application or a websockets app run on top of Node.js.

If your application does not have any CPU intensive computation, you can build it in Javascript top to bottom, even down to the database level if you use JSON storage object DB like MongoDB.

It is believed that more performance and scalability can be achieved by doing async processing on a single thread under typical web loads than the typical thread based implementation.ġ7) Mention the steps by which you can async in Node.js?ġ8) What are the pros and cons of Node.js? The two types of API functions in Node.js areĪ generic piece of code which runs in between several asynchronous function calls is known as control flow function.ĩ) Explain the steps how “Control Flow” controls the functions calls?įor async processing, Node.js was created explicitly as an experiment.

It provides an easy way to build scalable network programsħ) What are the two types of API functions in Node.js?.Web applications ( especially real-time web apps )Ħ) What is the advantage of using node.js?.Node.js can be used for the following purposes. It is an application architecture technique divided into two sections 1) Event Selection 2) Event Handling. In computer programming, event driven programming is a programming paradigm in which the flow of the program is determined by events like messages from other programs or threads.

It will be loaded into the machine memory to run the program, once the application is started.Ĥ) What does event-driven programming mean? I/O is the shorthand for input and output, and it will access anything outside of your application. 👉 Free PDF Download: Node.js Interview Questions & Answers > Node.js works on a v8 environment, it is a virtual machine that utilizes JavaScript as its scripting language and achieves high output via non-blocking I/O and single threaded event loop. Its multiple advantages over other server side languages, the prominent being non-blocking I/O. Node.js is a Server side scripting which is used to build scalable programs.
