QUESTION
I have seen the thinking in react article found here and in short it discusses how to break down components...
while i understand the concept in their example and it looks like this..
each colored box must be a separate component...
now I am creating a login page and i am a bit confused on how to break it down as most of it will not be reused somewhere else and i started to mix multiple concepts together I am wondering if you guys can help me sort my thoughts about this topic
screen shot of similar login page to the one i am making i have already colored components that should be separated based on the react official page docs so please let me know if I am thinking correctly and if any extra tips would be appreciated

Answered 2021-Jul-29 at 19:11React basically is component based library which is re-usable in projects.
For Example you can create the file InputComponent.js :
QUESTION
function renderRows(products) {
return products.map(({ name, price, category, stocked }, index, currArr) =>
// Is the category of the previous item in the array the same as the current item's category?
currArr[index - 1]?.category === currArr[index].category ? (
// If category is same, JUST render the product.
) : (
// If it's a new category, render 2 rows...
<>
)
);
}

Currently I'm building a Web App and looking to understand how state is implemented in a components hierarchy. Below is the structure of a component and it's children

Answered 2020-Dec-06 at 23:43Here is a super-contrived example using the strict structure you have given us here. Hopefully it will help explain how to think about state placement, then we can adjust it slightly to what you probably want in actual fact.
QUESTION
Thinking in React has mentioned about 2 terms namely
data model
model data
My question is what is the meaning of model in this ?
ANSWER
Answered 2020-Nov-30 at 02:02Model means the same for both, The only place I see them mention like you say is here:
There are two types of “model” data in React: props and state. It’s important to understand the distinction between the two;
I think they are speaking about how props or state model are handled.
Check this link out:
https://reactjs.org/docs/faq-state.html#what-is-the-difference-between-state-and-props
props (short for “properties”) and state are both plain JavaScript objects. While both hold information that influences the output of render, they are different in one important way: props get passed to the component (similar to function parameters) whereas state is managed within the component (similar to variables declared within a function).
Also:
https://github.com/uberVU/react-guide/blob/master/props-vs-state.md
Edit:
I would say you can "model data" with the existing "data models" which are props and state
check: https://reactjs.org/docs/faq-state.html#what-is-the-difference-between-state-and-props

QUESTION
im new to Svelte and build this component (https://reactjs.org/docs/thinking-in-react.html) to understand it a little better, after going through the tutorial. In Step 2 there is a section in the ProductTable class, where after an each loop theres the following statement
lastCategory = product.category;. Is there a way one can write a statemente after this each block? Below is my Code so far.
ANSWER
Answered 2020-May-05 at 20:57You cannot do that in Svelte. Instead you would do a simple reverse lookup:
