<h1 id="machine-learning-in-javascript-with-tensorflowjs"><a aria-hidden="true" tabindex="-1" href="#machine-learning-in-javascript-with-tensorflowjs"></a>Machine Learning in JavaScript with TensorFlow.js</h1>
Learn how to implement machine learning models directly in the browser using TensorFlow.js. We'll cover everything from basic neural networks to transfer learning.
<h2 id="getting-started"><a aria-hidden="true" tabindex="-1" href="#getting-started"></a>Getting Started</h2>
First, set up TensorFlow.js:
<pre><code class="hljs language-html">&#x3C;script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs">&#x3C;/script>
</code></pre>
<h2 id="basic-neural-network"><a aria-hidden="true" tabindex="-1" href="#basic-neural-network"></a>Basic Neural Network</h2>
Create a simple neural network:
<pre><code class="hljs language-javascript">// Define the model
const model = tf.sequential();
model.add(tf.layers.dense({ units: 128, activation: 'relu', inputShape: [28 * 28] }));
model.add(tf.layers.dropout({ rate: 0.2 }));
model.add(tf.layers.dense({ units: 10, activation: 'softmax' }));

// Compile the model
model.compile({
 optimizer: tf.train.adam(),
 loss: 'categoricalCrossentropy',
 metrics: ['accuracy'],
});
</code></pre>
<h2 id="training-the-model"><a aria-hidden="true" tabindex="-1" href="#training-the-model"></a>Training the Model</h2>
Train your model with data:
<pre><code class="hljs language-javascript">async function trainModel(model, data) {
 const history = await model.fit(
 data.trainImages,
 data.trainLabels,
 {
 epochs: 10,
 validationSplit: 0.2,
 shuffle: true,
 callbacks: {
 onEpochEnd: (epoch, logs) => {
 console.log(`Epoch ${epoch}: loss = ${logs.loss.toFixed(3)}`);
 }
 }
 }
 );
 return history;
}
</code></pre>
<h2 id="image-classification"><a aria-hidden="true" tabindex="-1" href="#image-classification"></a>Image Classification</h2>
Implement image classification:
<pre><code class="hljs language-javascript">async function classifyImage(model, imageElement) {
 // Pre-process the image
 const tensor = tf.browser.fromPixels(imageElement)
 .resizeNearestNeighbor([224, 224])
 .toFloat()
 .expandDims();

 // Make prediction
 const prediction = await model.predict(tensor).data();
 return prediction;
}
</code></pre>
<h2 id="transfer-learning"><a aria-hidden="true" tabindex="-1" href="#transfer-learning"></a>Transfer Learning</h2>
Use pre-trained models:
<pre><code class="hljs language-javascript">async function loadMobileNet() {
 const mobilenet = await tf.loadLayersModel(
 'https://storage.googleapis.com/tfjs-models/tfjs/mobilenet_v1_0.25_224/model.json'
 );
 
 // Remove the top layer
 const layer = mobilenet.getLayer('conv_pw_13_relu');

}
</code></pre>
<h2 id="real-time-predictions"><a aria-hidden="true" tabindex="-1" href="#real-time-predictions"></a>Real-time Predictions</h2>
Implement real-time video predictions:
<pre><code class="hljs language-javascript">async function predictWebcam() {
 const video = document.getElementById('webcam');
 
 while (true) {
 const prediction = await classifyImage(model, video);
 updateUI(prediction);
 await tf.nextFrame();
 }
}
</code></pre>
<h2 id="best-practices"><a aria-hidden="true" tabindex="-1" href="#best-practices"></a>Best Practices</h2>
<ol>
<li>Optimize model size for browser</li>
<li>Use WebGL backend when available</li>

<h1 id="mastering-typescript-advanced-patterns-and-best-practices"><a aria-hidden="true" tabindex="-1" href="#mastering-typescript-advanced-patterns-and-best-practices"></a>Mastering TypeScript: Advanced Patterns and Best Practices</h1>
TypeScript has become the go-to language for building large-scale JavaScript applications. In this post, we'll explore advanced patterns and best practices that will help you write more maintainable code.
<h2 id="generic-types"><a aria-hidden="true" tabindex="-1" href="#generic-types"></a>Generic Types</h2>
Generics are one of TypeScript's most powerful features. Here's how to use them effectively:
<pre><code class="hljs language-typescript">interface Repository&#x3C;T> {
 find(id: string): Promise&#x3C;T>;
 save(item: T): Promise&#x3C;void>;
 update(id: string, item: Partial&#x3C;T>): Promise&#x3C;void>;
 delete(id: string): Promise&#x3C;void>;
}

// Implementation example
class UserRepository implements Repository&#x3C;User> {
 async find(id: string): Promise&#x3C;User> {
 // Implementation
 }
 // ... other methods
}
</code></pre>
<h2 id="utility-types"><a aria-hidden="true" tabindex="-1" href="#utility-types"></a>Utility Types</h2>
TypeScript provides several utility types that can make your code more expressive:
<pre><code class="hljs language-typescript">interface User {
 id: string;
 name: string;
 email: string;
 password: string;
}

// Only pick certain properties
type UserDTO = Pick&#x3C;User, 'id' | 'name' | 'email'>;

// Make all properties optional
type PartialUser = Partial&#x3C;User>;

// Make all properties required
type RequiredUser = Required&#x3C;User>;
</code></pre>
<h2 id="type-guards"><a aria-hidden="true" tabindex="-1" href="#type-guards"></a>Type Guards</h2>
Type guards help you narrow down types in a type-safe way:
<pre><code class="hljs language-typescript">interface Bird {
 fly(): void;
 layEggs(): void;
}

interface Fish {
 swim(): void;
 layEggs(): void;
}

function isFish(pet: Fish | Bird): pet is Fish {
 return (pet as Fish).swim !== undefined;
}

function move(pet: Fish | Bird) {
 if (isFish(pet)) {
 pet.swim(); // TypeScript knows pet is Fish
 } else {
 pet.fly(); // TypeScript knows pet is Bird
 }
}
</code></pre>
<h2 id="conditional-types"><a aria-hidden="true" tabindex="-1" href="#conditional-types"></a>Conditional Types</h2>
Conditional types allow you to create more flexible type definitions:
<pre><code class="hljs language-typescript">type IsString&#x3C;T> = T extends string ? true : false;

// Examples
type A = IsString&#x3C;string>; // true
type B = IsString&#x3C;number>; // false

// More practical example
type ArrayOrSingle&#x3C;T> = T extends any[] ? T : T[];

function ensureArray&#x3C;T>(value: T): ArrayOrSingle&#x3C;T> {
 return Array.isArray(value) ? value : [value] as ArrayOrSingle&#x3C;T>;
}
</code></pre>
<h2 id="mapped-types"><a aria-hidden="true" tabindex="-1" href="#mapped-types"></a>Mapped Types</h2>
Mapped types help you transform existing types into new ones:
<pre><code class="hljs language-typescript">type Readonly&#x3C;T> = {
 readonly [P in keyof T]: T[P];
};

type Optional&#x3C;T> = {

<h2 id="best-practices"><a aria-hidden="true" tabindex="-1" href="#best-practices"></a>Best Practices</h2>
<ol>
<li>
Use strict mode
<pre><code class="hljs language-json">{
 "compilerOptions": {
 "strict": true
 }
}
</code></pre>
</li>
<li>
Prefer interfaces over type aliases for object types
<pre><code class="hljs language-typescript">// Good
interface User {
 name: string;
 age: number;
}

// Less ideal for objects
type User = {
 name: string;
 age: number;
};
</code></pre>
</li>
<li>
Use const assertions for literal types
<pre><code class="hljs language-typescript">const config = {
 endpoint: "api.example.com",
 method: "POST"
} as const;
</code></pre>
</li>
<li>
Leverage discriminated unions
<pre><code class="hljs language-typescript">interface Success {
 type: "success";
 data: unknown;
}

interface Error {
 type: "error";
 message: string;
}

type Result = Success | Error;

<h2 id="conclusion"><a aria-hidden="true" tabindex="-1" href="#conclusion"></a>Conclusion</h2>
TypeScript's type system is incredibly powerful when used correctly. By understanding and applying these advanced patterns, you can write more maintainable and type-safe code. Remember that types are not just for catching errors - they're also documentation for your code and tools for better developer experience.

const HeavyComponent = lazy(() => import('./HeavyComponent'));

function App() {
 return (
 &#x3C;Suspense fallback={&#x3C;Loading />}>
 &#x3C;HeavyComponent />
 &#x3C;/Suspense>
 );

<pre><code class="hljs language-jsx">function ExpensiveComponent({ data, onUpdate }) {
 // Memoize expensive calculations
 const processedData = useMemo(() => {
 return data.map(item => expensiveOperation(item));
 }, [data]);

 // Memoize callbacks
 const handleUpdate = useCallback(() => {
 onUpdate(processedData);
 }, [onUpdate, processedData]);

 return (

 );
}
</code></pre>
<h2 id="state-management-optimization"><a aria-hidden="true" tabindex="-1" href="#state-management-optimization"></a>State Management Optimization</h2>
Optimize Redux or other state management:
<pre><code class="hljs language-jsx">// Bad: Re-renders all items
function ItemList({ items }) {
 return (
 &#x3C;div>
 {items.map(item => (
 &#x3C;Item key={item.id} {...item} />
 ))}
 &#x3C;/div>
