Can you use document in NodeJS?

Yes, there are ways to create documents in Node.

When NodeJS is not recommended for use?

js receives a CPU bound task: Whenever a heavy request comes to the event loop, Node. js would set all the CPU available to process it first, and then answer other requests queued. That results in slow processing and overall delay in the event loop, which is why Node. js is not recommended for heavy computation.

Where does NodeJS require look for modules?

node_modules
Node will look for your modules in special folders named node_modules . A node_modules folder can be on the same level as the current file, or higher up in the directory chain. Node will walk up the directory chain, looking through each node_modules until it finds the module you tried to load.

How much RAM does NodeJS need?

256 MB is sufficient amount of RAM to run Node. js (e.g. on Linux VPS instance), assuming no other memory-hog software is run.

Can I learn node js without knowing JavaScript?

Should I learn JavaScript before Node JS? If you have taken another programming course before (like Python) then you have the proper programming foundation and can go ahead and start learning Node JS without taking a JavaScript course. You can pick up the fundamentals of JS while you build servers with Node.

Is node JS frontend or backend?

A common misconception among developers is that Node. js is a backend framework and is only used for building servers. This isn’t true: Node. js can be used both on the frontend and the backend.

Is node js a programming language?

JavaScript is the only language that Node.js supports natively, but many compile-to-JS languages are available. As a result, Node.js applications can be written in CoffeeScript, Dart, TypeScript, ClojureScript and others. Node.js is primarily used to build network programs such as Web servers.

Is NodeJS good for large applications?

It is suitable for large enterprise projects that do complex and complicated computations and data processing. The comparison in terms of development time between Node. js and Java is that, Node. js is easier to learn than Java, leading to faster development when using Node.

Can we write node js test without external library?

If you’ve ever written tests for a Node. js application, chances are you used an external library. However, you don’t need a library to run unit tests in Javascript.

Why do you need separate modules in node JS?

Each module in Node. js has its own context, so it cannot interfere with other modules or pollute global scope. Also, each module can be placed in a separate . js file under a separate folder.
