I'm new to Date-FNS and I need to get this example to work in Vue.js/Quasar:

import { startOfISOWeek, endOfISOWeek } from 'date-fns'

<span> {{ startOfISOWeek }} </span>
<span> {{ endOfISOWeek }} </span>

export default defineComponent({
    data() {
        return {
            startOfISOWeek,
            endOfISOWeek 
    }
  },
})

How do I get this to work?
