React Js Maxad kataqaanaa?

React JS waa maktabad JavaScript oo loogu talagalay in lagu dhiso interface-yada isticmaale (user interfaces) ee websiteska. Waxaa sameeyay Facebook (hadda Meta) 2013-kii , waana mid ka mid ah JavaScript frameworks-ka ugu caansan ee suuqa maanta, taas darteed barashadeeda waa maalgelin wanaagsan mustaqbalkaaga!.

Waxyaalaha Muhiimka ah ee React:

1. Component-based (Qaybaha) – React waxay kuu ogolaataa inaad UI-ga u kala qaybiso qaybyo yar yar oo dib loo isticmaali karo. Tusaale ahaan, button, card, ama navbar waxay noqon kartaa component gaar ah.

2. Virtual DOM – React waxay isticmaashaa “Virtual DOM” si ay u hesho wax ka qabashada degdeg ah. Tani waxay ka dhigtaa websiteska inay si degdeg ah u shaqeeyaan.

3. JSX Syntax – React waxay isticmaashaa JSX, kaas oo ah isku dar HTML iyo JavaScript. Tani waxay sahashaa qorista code-ka.

4. One-way Data Flow – Xogta waxay ku socotaa hal jiho keliya (hal-abar), taas oo fududeyneysa fahamka sida app-ka u shaqeeyo.

5. Reusable (Dib loo isticmaali karo) – Markaad component sameyso, waxaad dib ugu isticmaali kartaa meelo badan oo kala duwan.

Tusaale Fudud:

javascript

function Welcome() {

  return <h1>Soo dhawoow React!</h1>;

}

React waxaa badanaa loo isticmaalaa dhisidda:

  • Single Page Applications (SPAs)
  • Mobile apps (React Native la isticmaalaya)
  • Websiteska casriga ah ee interactive ah

Fundamentals of React Js

Waa kuwan fundamentals-ka React ee muhiimka ah oo aad u baahan tahay inaad barato:

1. Components (Qaybaha)

Waa dhismaha aasaasiga ah ee React. Laba nooc ayaa jira:

  • Functional Components – functions fudud oo soo celiya JSX
  • Class Components – classes hore loo isticmaali jiray (hadda waa in yar)

javascript

function Magac() {

  return <h1>Waan ku salaamay!</h1>;

}

2. JSX (JavaScript XML)

Waa syntax kuu oggolaanaya inaad HTML ku qorto JavaScript dhexdiisa.

javascript

const element = <h1>Halkan waa JSX</h1>;

3. Props (Properties)

Waa sida aad xog ugu gudbiso component ilaa component kale, sida parameters function.

javascript

function Salam(props) {

  return <h1>Salam {props.magac}!</h1>;

}

4. State

Waa xogta ka beddelanta component-ka. Marka state beddesho, component-ka waa la cusbooneysiiyaa.

javascript

const [count, setCount] = useState(0);

5. Hooks

Functions gaar ah oo kuu oggolaanaya inaad state iyo features kale ku isticmaasho functional components:

  • useState – state-ka maareynta
  • useEffect – shaqooyin dhinac ah (side effects) sida API calls
  • useContext – xogta wadaagida components dhexdooda

6. Event Handling

Maaraynta dhacdooyinka sida clicks, form submissions:

javascript

function handleClick() {

  alert(‘Button la riixay!’);

}

<button onClick={handleClick}>Riix</button>

7. Conditional Rendering

Soo bandhigida shay shuruudo ku saleysan:

javascript

{isLoggedIn ? <Dashboard /> : <Login />}

8. Lists iyo Keys

Soo bandhigida liisaska xogta:

javascript

items.map(item => <li key={item.id}>{item.name}</li>)

9. Forms

Maaraynta gelinta user-ka iyo forms.

10. Component Lifecycle

Fahamka sida components ay u dhashaan, u cusboonaadaan, ugu baaba’aan.

Kuwani waa asaaska.
