+### ການ render ເລີ່ມຕົ້ນ {/*initial-render*/}
 
-When your app starts, you need to trigger the initial render. Frameworks and sandboxes sometimes hide this code, but it's done by calling [`createRoot`](/reference/react-dom/client/createRoot) with the target DOM node, and then calling its `render` method with your component:

-Once the component has been initially rendered, you can trigger further renders by updating its state with the [`set` function.](/reference/react/useState#setstate) Updating your component's state automatically queues a render. (You can imagine these as a restaurant guest ordering tea, dessert, and all sorts of things after putting in their first order, depending on the state of their thirst or hunger.)

-* **On initial render,** React will call the root component.
-* **For subsequent renders,** React will call the function component whose state update triggered the render.
+* **ໃນການ render ເລີ່ມຕົ້ນ,** React ຈະເອີ້ນໃຊ້ root component.

-This process is recursive: if the updated component returns some other component, React will render _that_ component next, and if that component also returns something, it will render _that_ component next, and so on. The process will continue until there are no more nested components and React knows exactly what should be displayed on screen.
+ຂະບວນການນີ້ເປັນແບບເອີ້ນຊໍ້າ: ຖ້າ component ທີ່ອັບເດດ return component ອື່ນ, React ຈະ render component _ນັ້ນ_ ຕໍ່ໄປ, ແລະ ຖ້າ component ນັ້ນ return ບາງຢ່າງ, ມັນຈະ render component _ນັ້ນ_ ຕໍ່ໄປ, ແລະ ອື່ນໆ. ຂະບວນການຈະດຳເນີນຕໍ່ໄປຈົນກວ່າຈະບໍ່ມີ component ທີ່ຊ້ອນກັນອີກຕໍ່ໄປ ແລະ React ຮູ້ວ່າແມ່ນຫຍັງຈະສະແດງເທິງໜ້າຈໍ.

+ການ render ຕ້ອງເປັນ [ການຄຳນວນ pure](/learn/keeping-components-pure):
 
-* **Same inputs, same output.** Given the same inputs, a component should always return the same JSX. (When someone orders a salad with tomatoes, they should not receive a salad with onions!)
-* **It minds its own business.** It should not change any objects or variables that existed before rendering. (One order should not change anyone else's order.)
+* **input ດຽວກັນ, output ດຽວກັນ.** ເມື່ອພິຈາລະນາ input ດຽວກັນ, component ຄວນຈະ return ຄ່າ JSX ດຽວກັນສະເໝີ . (ເມື່ອມີຄົນສັ່ງສະລັດກັບໝາກເລັ່ນ, ພວກເຂົາບໍ່ຄວນໄດ້ຮັບສະລັດກັບຫອມບົວ!)

-Otherwise, you can encounter confusing bugs and unpredictable behavior as your codebase grows in complexity. When developing in "Strict Mode", React calls each component's function twice, which can help surface mistakes caused by impure functions.

 #### Optimizing performance {/*optimizing-performance*/}
 
-The default behavior of rendering all components nested within the updated component is not optimal for performance if the updated component is very high in the tree. If you run into a performance issue, there are several opt-in ways to solve it described in the [Performance](https://reactjs.org/docs/optimizing-performance.html) section. **Don't optimize prematurely!**
