On Lesson 3

[Ohyathatscool]

Currently on Lesson 3 and while I'm kind of understanding the syntax I feel as I am not understanding what I'm doing. Is this normal? How much should I know how to do at this point? I do feel a little discouraged but I will complete the course. My main problem is seeing how everything works together.

Completing the course should not be your goal, rather, understanding everything the course offers should be the mindset instead.

I would recommend going through a vanilla JavaScript course, blockchain fundamentals and preferably expertise/overview of OOP if you are struggling to grasp things. This much should be enough

If you already are familiar with the fundamentals, what is the issue here? "just seeing how everything works together" is a vague description, I can help if you provide some context.

Well first this confuses me.
From lesson 1

People[ ] public people;

So am I am understanding this correctly "People[ ]" is pointing back to the struct People and creating and array and "people" is the variable to the array.

function addPerson(string memory _name, uint256 _favoriteNumber) public {
people.push(People(_favoriteNumber, _name));
nameToFavoriteNumber[_name] = _favoriteNumber;

I understand that "people.push" is adding to the "People[ ] array" but why do we need to add "People" in the paratheses again. I thought the point of "people" was so we can use that instead of "People"

Hope this makes senses and again thanks for the help.

Ok, I got it. I would recommend going through an OOP-language course.

People[] public people is an array people of scope public which can contain instances of People objects.

people.push(People(_favoriteNumber, _name)); We are pushing People(_favoriteNumber, _name) (this is basically a People instance with specific arguments) to the people array.

Thank you so much! Is there any course you recommend?

[krakxn]

FreeCodeCamp should be sufficient, or any extensive OOP course. Do not waste time building projects unless you want to pursue this field further, because OOP is incorporated widely (unless, of course, front-end w/ exception for JavaScript).

If I had to start all over again, I would master an OOP language before moving on. In retrospect, that was the biggest benefit I had—as I could be versatile from thereon—and could easily be familiar with any other language.

I literally take like 2 hours for every half hour of class and I have i am only one year into Javascript....its better you have some understanding of what your doin...even if it takes longer, you'll be happier in the end...no one is judging...take your time and fiddle so you get a better feel of it.. Its worth it in the the end make the $$$$

[Ohyathatscool]

Thanks. Yes I have done a little bit of JavaScript but what I really wanted to learn was Solidity so I figured I'll just focus here. Just have to take my time.

People[] is the model/class and type public is access people is the array name itself hope this helps

Yes, it's slowing starting to click. Thanks!

[CramerJ1470]

Honestly this took me a couple head turns at first too. I watched some segments a couple times to get it and cut and paste pieces of code I didn’t understand into google (sorry I’m sure you do that too)….def no a javascript order in this case.
