Working with NPM is mandatory foundational knowledge as you learn Node.js. Node Package Manager (NPM) allows developers to create shareable modules and share them with the world - including us! Instead of re-creating the wheel, we can search for existing packages to import into our projects that meet our needs.

Good intro to NPM, I like NPM but I often see people install a lot of dependencies just to get benefit from some basic stuffs, Thirsty for more coding, Thanks Dave

[@DaveGrayTeachesCode]

Very true, Ahmad. It can be abused. At the same time, it has many good uses and is foundational knowledge for working with Node JS. Thanks for the comment! 💯

thanks bro!

hey Dave, I know this is off topic. but can u explain this function. const range = (start, stop, step) => Array.from({ length: (stop - start) / step + 1}, (_, i) => start + (i * step)); from mdn under array.from as well as let range = { from: 1, to: 5 }; // 1. call to for..of initially calls this range[Symbol.iterator] = function() { // ...it returns the iterator object: // 2. Onward, for..of works only with this iterator, asking it for next values return { current: this.from, last: this.to, // 3. next() is called on each iteration by the for..of loop next() { // 4. it should return the value as an object {done:.., value :...} if (this.current

[@DaveGrayTeachesCode]

Definitely off the topic of this video tutorial, but I could do a tutorial on the topic you are asking about sometime. 😀 MDN is a great source to look up each part of your question such as symbol.iterator: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol/iterator

[@MguelMallet]

hi Dave Im using the latest version of node. One thing i noted when using the function to format date fron date-fns. the syntax as you write it result in application crash telling me date is not defined. the variable date need to be defined first like const d = new date(). then we use the date format function: console.log(format(d, 'yyyy-MMM-dd') then i get the proper result.

[@DaveGrayTeachesCode]

You must have missed where I created the new date because I did not crash and this has not changed due to a Node release.

[@jiweihe3413]

thanks. I encountered some problem installing nodemon... It cannot be run after installation: "nodemon : The term 'nodemon' is not recognized as the name of a cmdlet, function, script file, or operable program. "

[@DaveGrayTeachesCode]

Follow their installation guide here: www.npmjs.com/package/nodemon

[@okumorphilip8087]

Maybe you should apply for a lecturing Job Dave

[@DaveGrayTeachesCode]

Thanks - I was previously at a university full-time. Now part-time university and full-time dev.

[@michaelrodrigues6372]

is there a repo of this node course in your github?

[@DaveGrayTeachesCode]

Hi Michael - not for the first 5 chapters as they are only examples. Starting with Chapter 6, each lesson has source code available here: github.com/gitdagray/node_js_resources

[@kingsleyunorji5044]

whenever i type this command "npm i nodemon -g " it shows this changed 32 packages, and audited 33 packages in 1s 3 packages are looking for funding run `npm fund` for details found 0 vulnerabilities i then went ahead to type nodemon in the terminal and i get this nodemon: command not found any advise to give please

[@DaveGrayTeachesCode]

The first part of the message is a standard type of return after installing a package with npm. The second part - why just type nodemon in the terminal? It must run on Node. In this video, I believe I show how to set up the script you need in your package.json file to run it.

First, I want to say thank you and great job with this video. However, even though you say for beginners, I feel your tutorials are hard for someone who's not familiar with what your teaching and is actually a beginner. When i watch your tutorials, i need to go learn elsewhere first then come back here to enhance what i know and even at that the new concepts i get from your video are always hard to understand. Just constructive criticism, great video still!
