Answers for "check object array is empty javascript"

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();
}

javascript check if object is null or empty

if (typeof value !== 'undefined' && value) {
    //deal with value'
};
