react object not empty code example

Example 1: react native object is empty

//when this.state.errors object is empty 
if (Object.keys(this.state.errors).length == 0) {
  this.props.updateUser(user);
  this.props.navigation.goBack();
}

Example 2: javascript test for empty object

// because Object.entries(new Date()).length === 0;
// we have to do some additional check
Object.entries(obj).length === 0 && obj.constructor === Object
