When I use new Date(); in react native to create a new date or time I get the error:
TypeError: undefined is not a constructor (evaluating ‘new _reactNative.Date()’)
What could be causing this? Is there something I am not importing into react Native?
import React from 'react'; import { StyleSheet, View, Text, Button, Image, TouchableOpacity, Date, ScrollView } from 'react-native'; export default class AddAProfile extends React.Component { const date = new Date(); render () { return ( <View> {this.date} </View> ) }} export default AddAProfile;

There are several issues here that are fogging things up. First of all, classes in React should have a constructor, and if you’re going to use class parameters, the constructor needs a call to super(). Second of all, there isn’t a View component in the class, so create one or use elements instead. Thirdly, in order to display the date, you will need to chain a toString() at the end.
See the code below.
class AddAProfile extends React.Component { constructor() { super(); this.d = new Date().toString(); } render() { return( <p>{this.d}</p> ) } }
