I didn’t need to watch the video but wanted to give you the view. But I actually did learn something...I didn’t know the console still printed out the same input on separate lines when you kept clicking button haha I thought the new thing was it just showed how many times it was pressed until you logged something new

Hey John, thanks for all your work both here and for the amazing courses you publish on udemy! You are the best! I have a question: do you foresee to do some courses on unit testing? Or maybe a dedicated course on unit testing? or reuse existing courses for unit testing?. Thanks for all your work!!

Was wondering what editor and plugins do you use, the auto-reformatting blew my mind

@CodingAddict 2 жыл бұрын

Hello, Yes I use built in prettier extension (but I believe it comes as default now) and I added this code in settings.json { "editor.formatOnPaste": true, "editor.formatOnSave": true, "editor.defaultFormatter": "esbenp.prettier-vscode", "[javascript]": { "editor.defaultFormatter": "esbenp.prettier-vscode" } You can find my entire setup here github.com/john-smilga/VS-CODE-SETUP

It depends. If you are looking for front-end content then React, if backend then Node.js

In line 19, does 'value' equal 'fullName'? Is that what the callback function is having passed into it?

@AaronM 3 жыл бұрын

sorry, dumb question, but what is the purpose of this? i'm still learning, but if the callback is defined in the file (or i presume imported from another module) you can also just call it from within another function without explicitly passing it in as an argument. makeUpperCase and reverseString don't need to be passed in as args of handleName. again, sorry, I'm just trying to wrap my head around why you'd want to do this. update: i guess maybe i wrote the above too soon, cuz it looks like my question is kind of answered with the button example, where you're not defining the logic. I'm coming from more of a Node point of view, rather than browser point of view, or something, where you'd write out all the logic yourself? Is there another real world example that could help solidify this for me?

@CodingAddict 3 жыл бұрын

Hmm. Have you ever used map or filter functions?

@AaronM 3 жыл бұрын

@@CodingAddict I’ve used map in Python, which I imagine is similar in JS. I guess I didn’t consider that since that’s the way that built-in module is written, vs why one would intentionally write with callbacks in mind, but maybe it’s just as simple as, cuz that’s what they want it to do? Sometimes when I write (bad) functions, I’ll call multiple other functions too. So I think I was wondering, if I intend to call them, do I NEED to pass ALL of them in as args, or do I just have the OPTION to pass them as args?

@CodingAddict 3 жыл бұрын

Yes, as far as building your own functions that take in callback functions, I see what you are saying, often times you can make an argument that it's easier to just code all the login inside of the function. But it's important to understand the general concept, since callback functions are used all over the javascript as well as the node, and many different libraries.

@AaronM 3 жыл бұрын

@@CodingAddict I agree with you about understanding how it works, and appreciate your responses. I think maybe as I learn more and get more exposure, it will “click.” It may also be that I’m too rigid in my thinking - usually when I write my logic, I tend to write with a specific return in mind, hence my “hard coding” functions inside other functions. But I can at least recognize that by using callbacks, that return can be more fluid/flexible. Either way, I appreciate the response and thanks for the work you’re doing to help teach us.
