At 9:55,
The '...' (spread operator) is commonly used in useState hooks to update state. The spread operator helps you copy the existing state while modifying specific parts of it without directly mutating the original state.
i.e. '...form' means keeping everything same in this form we only change
[e.target.name] to e.target.value

The setForm function used above is just a shorthand version of <<
setform(()=>{
let objcopy = {...form}
objcopy[e.target.name] = e.target.value
return objcopy
})>>

Kisko kisko galat Installing VSCode wale video ka notification aaya 😅

Harry Bhai, you have used useState to handle input, it means on each change event, the state is changing, as a result the app is getting rerendered for each key stroke, wouldn't it be better to handle this using useRef instead of useState,
