如何将数组添加到MEAN.JS中的javascript服务器端模型

I am using MEAN.JS and I have created a module for projects. I would like to add tasks to these projects and I would like to do it with a multi-dimensional array. I would like the array to include a task.description and a task.status which would both be strings. I think I understand the client-side part of my project and I know there are still other files. However, I believe this will make the question as simple as possible, as I am struggling to get my profile developed on this site. I will however include controller.js, so I can get this working and hopefully give credit for a correct answer. I am using MEAN.JS and I have created a module
