Mbinu moja kama hiyo ni [kanuni ya uwajibikaji mmoja (single responsibility principle)](https://en.wikipedia.org/wiki/Single_responsibility_principle), yaani, kijenzi kinapaswa kufanya jambo moja tu. Ikiwa kitaishia kukua, inapaswa kigawanywe kiwe vijenzi vidogo.
 * **CSS**--fikiria ni nini ungetengeneza viteule vya darasa. (Hatahivyo, vijenzi ni vidogo kwa kiasi fulani.)
 * **Design**--fikiria jinsi unavyoweza kupanga safu za muundo.
-=======
-* **Programming**--use the same techniques for deciding if you should create a new function or object. One such technique is the [separation of concerns](https://en.wikipedia.org/wiki/Separation_of_concerns), that is, a component should ideally only be concerned with one thing. If it ends up growing, it should be decomposed into smaller subcomponents.
-* **CSS**--consider what you would make class selectors for. (However, components are a bit less granular.)

 Katika hatua ya awali, ulipata vipande viwili vya hali katika programu hii: maandishi ya ingizo ya utafutaji, na thamani ya kisanduku cha kuteua. Katika mfano huu, daima huonekana pamoja, kwa hiyo ni mantiki kuviweka katika sehemu moja.

      * `SearchBar` inahitaji kuonyesha hali hiyo (maandishi ya utafutaji na thamani ya kisanduku cha kuteua).
 1. **Tafuta mzazi wao wa kawaida:** Kijenzi mzazi cha kwanza ambacho vijenzi vyote viwili hushiriki ni `FilterableProductTable`.
 2. **Amua mahali pa kuishi**: Tutaweka maandishi ya kichujio na thamani za hali zilizochaguliwa katika `FilterableProductTable`.
-=======
-1. **Identify components that use state:**
-    * `ProductTable` needs to filter the product list based on that state (search text and checkbox value).
-    * `SearchBar` needs to display that state (search text and checkbox value).
-2. **Find their common parent:** The first parent component both components share is `FilterableProductTable`.
-3. **Decide where the state lives**: We'll keep the filter text and checked state values in `FilterableProductTable`.

-## Step 5: Add inverse data flow {/*step-5-add-inverse-data-flow*/}
-
-Currently your app renders correctly with props and state flowing down the hierarchy. But to change the state according to user input, you will need to support data flowing the other way: the form components deep in the hierarchy need to update the state in `FilterableProductTable`.
-
-React makes this data flow explicit, but it requires a little more typing than two-way data binding. If you try to type or check the box in the example above, you'll see that React ignores your input. This is intentional. By writing `<input value={filterText} />`, you've set the `value` prop of the `input` to always be equal to the `filterText` state passed in from `FilterableProductTable`. Since `filterText` state is never set, the input never changes.
->>>>>>> 7b6c3ceb9dd97249e9dce4a8a94e61aed6424698
 
 You want to make it so whenever the user changes the form inputs, the state updates to reflect those changes. The state is owned by `FilterableProductTable`, so only it can call `setFilterText` and `setInStockOnly`. To let `SearchBar` update the `FilterableProductTable`'s state, you need to pass these functions down to `SearchBar`:

 Unlike other hooks, `use` can be called inside conditions and loops — but it must always be called for the Promise itself. Never read `promise.status` or `promise.value` directly to bypass `use`; always pass the Promise to `use` and let React handle it.
