Your application needs a way to capture information about a household on a property that is being redeveloped. Develop a UI for building a household up from individual people.
You have been given an HTML page with a form and a placeholder for displaying a household.
In the given index.js file, replace the "Your code goes here" comment with JavaScript that can:
- Validate data entry (age is required and > 0, relationship is required)
- Add people to a growing household list
- Remove a previously added person from the list
- Display the household list in the HTML as it is modified
- Serialize the household as JSON upon form submission as a fake trip to the server
Do not modify the given index.html file in any way. You're of course still allowed to modify the DOM through Javascript.
You must write JavaScript, not a language that compiles down to JavaScript. You may use ES3, ES5/5.1, or ES6 standard. Assume the capabilities of a modern mainstream browser in wide use, i.e. consider the trade-offs if you want to use bleeding-edge features. No 3rd party libraries -- i.e., no jQuery.
The display of the household list is up to you.
On submission, put the serialized JSON in the provided "debug" DOM element and display that element.
After submission the user should be able to make changes and submit the household again.
You do not need to add validations around anything other than the age and relationship requirements described above. It's ok for someone to add 35 parents.
The focus here is on the quality of your JavaScript, not the beauty of your design. The controls you add around viewing and deleting household members should be usable but need not be much to look at.
