import { openai } from '@ai-sdk/openai';



const { text } = await generateText({

  model: openai('gpt-4'),

  prompt: 'Write a hello world program',

});



// Streaming responses became standard

import { streamText } from 'ai';



const result = streamText({

  model: openai('gpt-4'),

  prompt: 'Tell me a story',

});



for await (const chunk of result.textStream) {

  process.stdout.write(chunk);

}

  let doubled = $derived(count * 2);

  

  function increment() {

    count += 1;

  }

</script>



<button onclick={increment}>

  {count} x 2 = {doubled}

</button>

Solid.js

Solid.js gained attention in 2024:

// Fine-grained reactivity

function Counter() {

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

  

  return (

    <button onClick={() => setCount(count() + 1)}>

      Count: {count()}

    </button>

  );

}

5. CSS Evolution

CSS New Features

CSS gained many new features in 2024:

/* Container queries */

@container (min-width: 400px) {

  .card { grid-template-columns: 2fr 1fr; }

}



/* Nested selectors */

.card {

  background: white;

  & .title { font-size: 1.5rem; }

  & .content { padding: 1rem; }

}



/* :has() selector */

.card:has(img) {

  display: grid;

}



/* Subgrid */

.parent { display: grid; grid-template-columns: 1fr 1fr; }

.child { display: grid; grid-template-columns: subgrid; }



/* @layer */

@layer base, components, utilities;

    return target.apply(this, args);

  };

}



class Calculator {

  @log

  add(a: number, b: number) {
