The value to compare against.
A function that takes a value and returns the result of a strict equal with toCompare.
This function is useful within React components to keep your code looking clean when a value must be compared against multiple times.
type Props = { status?: 'stale' | 'pending' | 'fulfilled' }
const Component = (props: React.PropsWithChildren<Props>) => {
const { status } = props
const isStatus = createEq(status)
// no longer need to write `status === '...'` multiple times
if (isStatus('stale')) {
return <div>Stale</div>
}
if (isStatus('pending')) {
return <div>Pending</div>
}
if (isStatus('fulfilled')) {
return <div>Fulfilled</div>
}
return null
}
Accepts a value and returns a function that will compare against it.
