useIsEmpty

useIsEmpty provides small helpers to check whether a value should be treated as empty.

What It Considers Empty

• undefined, null, and ''
• arrays with length === 0
• plain objects with no keys (checked via lodash-es isEmpty)

Everything else is treated as not empty.

Example

import { useIsEmpty } from '@blueprint-ts/core/vue'

const { isEmpty, isNotEmpty } = useIsEmpty()

isEmpty(null) // true
isEmpty('') // true
isEmpty([]) // true
isEmpty({}) // true

isNotEmpty('Hello') // true
