How to Get Current Date & Time in React

useEffect(() => {
const dateString = Date.now()
    const formatDate = (dateString) => {
      const options = { year: "numeric", month: "long", day: "numeric"}
      return new Date(dateString).toLocaleString(undefined, options)
    }
    alert(JSON.stringify(formatDate(dateString)))
}, [])

If don't want to use options and just want to use dd/mm/yyyy format then use below code.

const dateString = Date.now()

    const formatDate = (dateString) => {

      return new Date(dateString).toLocaleString('en-GB')

    }

alert(JSON.stringify(formatDate(dateString)))
