1:Can you tell me about the Node.js?
2:Can you list the two arguments which are taken by the async.queue?
Answer :Following are the two arguments which are taken by the async.queue. They are,
Concurrency value
Task function
Concurrency value.
Task function.
3:Explain about the working of Node.js?
Answer :It works on the v8 environment. This is a VM which utilizes the JavaScript as their scripting language. As a result, we can able to get high output. This is possible through the I/O which are non-blocking as well as event loop which are single threaded.
4:Can you explain about the CLI in the Node.js?
Answer :In general, we can able to say CLI as a utility / a program in our PC. Here the users are allowed to type the commands just for performing the actions. Also, running scripts instead of clicking on screen. We have many types of CLI. These are based on the OS which we use. Following are few of them. They are,
Terminal of the Mac.
Shell.
Terminal on the Unix as well as Ubuntu.
Command line.
Command Prompt.
Bash on the Linux.
Powershell on the windows.

5:Can you tell me about function calls which is controlled by the control Flow?
Answer :Following are the steps involved in controlling the function calls by the control flow. They are,
Order of the execution is controlled.
Data is collected.
Concurrency is limited.
Next steps in the program should be called.

6:Can you list the programming language used for writing the Node.js?
Answer :Following are the list of programming language used for writing the Node.js. They are,
JavaScript.
C++.
C.
With the help of JavaScript Engine of V8, we can able to convert the codes of the JavaScript to the C++. This is Open source engine of the Google.

7:Explain about the function of the control flow?
Answer :The codes which are generic piece which runs between many function calls of asynchronous is called as the control flow.
8:Can you tell me about the JavaScript Engine?
Answer :Using this engine, we can able to convert the codes of the JavaScript to anything which is understand by the computer processor.
9:Can you list the 2 types of the API in the Node.js?
Answer : Following are the 2 types of the API in the Node.js. They are,
Synchronous, the functions which are blocking.
Asynchronous, the functions which are non-blocking.
Synchronous, the functions which are blocking.
Asynchronous, the functions which are non-blocking.
10:Can you explain about the I/O?
Answer : I/O is short form of input as well as output. We can able to access all things outside of our apps with the help of this. This will load in the memory of the machine for running the program. This is once the app is started.
11:Can you list the advantages of the Node.js?
Answer :Following are some of the advantages of the Node.js. They are,
Fast.
Building the scalable networking program is easy.
Concurrency is very high.
Everything is asynchronous.
No blocks.

12:Can you tell me about why the Node.js is the single threaded?
Answer :We explicitly created the node.js as experiment for the async process. Generally, there is a belief that we can achieve the performance as well as scalability. This is possible only when we follow async process on the single threaded.
13:What is mean by the programming of event- driven?
Answer :In the computer programming, it is programming paradigm. Here we can able to determine the programing flow with the help of the events. Just like messages from the other programs / threads. This is app architecture technique. Generally, we divide it into 2 sections. They are,
Event Handling.
Event Selection.
Event Handling.
Event Selection.
14:Can you list down the task which you should asynchronous while using event loop?
Answer : Following are the task which we should asynchronous while using event loop. They are,
All thing which need blocking.
High computing.
I/O operations.
All thing which need blocking.
High computing.
I/O operations.
15:Can you list me where you can use the node.js?
Answer :Following are some of the purpose where we can able to use the node.js. They are,
General purpose apps.
Distributed system.
Network apps.
Web apps.
General purpose apps.
Distributed system.
Network apps.
Web apps.
16:Can you tell me about the ECMAScript?
Answer :The JavaScript will be based on standard. We create this for standardizing the JavaScript. Generally, we use this for the Client-side scripts on WWW. Also, use by the node.js to write the server apps as well as services.
17:Explain about the NPM?
Answer :For the programming language of the JavaScript, NPM is the package manager. This is default PM. It is used to install as well as update the package & module of the JavaScript.
18:Can you tell me about the CommanJs Modules?
Reusable.
Namespace of the code.
20:Can you able to access the DOM in the Node?
Answer :No, we can’t able to access the DOM in the Node.
21:Can you able to run the nodes on the windows?
AnswerYes, we can able to run the nodes on the windows. We can able to download MSI from the official website. http://nodesjs.org/download/
22:What are the steps for async in the nodes?
Answer :Following are the steps which we need to follow to async in the nodes. They are,
Function composition.
1st class fn.
Event loop.
Callback counter.

Event loop.
Callback counter.
23:Can you name the author of the Node.js?
Answer :Ryan Dahl is the author of the Node.js.24:How will you check the version of the installed Node.js?
Answer :We want to implement the command node -v for checking the version of the installed Node.js.
25:Can you able to tell me the commonly used framework in the node.js?
Answer :The commonly used framework in the node.js is Express.
