The state of frontend frameworks
The state of frontend frameworks
const Example = () => {
const [label, setLabel] = useState("")
const updateLabel = (event) => {
setLabel(event.target.value)
}
return (
<div>
<input type="text" value={label} onChange={updateLabel} />
<p>{label}</p>
</div>
)
}The state of frontend frameworks
The hooks you have to use:
- useCallback
- useMemo
- useRef
- useImperativeHandle
- ...
The hooks you kind of want to use:
- useState
- useEffect
The state of frontend frameworks
- Static Site Generators (Gatsby, ...)
- Server Side Rendering (Next, ...)

// Example.svelte
<script>
let label;
</script>
<div>
<input bind:value={label} />
<p>{label}</p>
</div>
The futur of frontend frameworks
The futur of frontend frameworks

- We compile to JavaScript anyway
- We want more language features and types
- We want less work done on the browser
So the next question is...
...is JavaScript the right language?
