Im lost here. Help anyone?

I have to return tasks as if they were done. Should i use an if statement here somehow?

app.js 
const todos = [
    {
        todo: 'Buy apples',
        done: false
    },
    {
        todo: 'Wash car',
        done: true
    },
    {
        todo: 'Write web app',
        done: false
    },
    {
        todo: 'Read MDN page on JavaScript arrays',
        done: true
    },
    {
        todo: 'Call mom',
        done: false
    }
];
let unfinishedTasks;

unfinishedTasks = todos
  .filter(tasks => tasks.)
  .map();



// unfinishedTasks should be: ["Buy apples", "Write web app", "Call mom"]
// Write your code below

You don't actually write an if statement, because that is essentially what the filter is doing. You want the filter to check like it was an if statement, so whatever returns true gets returned as an array. Then you are going to use .map to return just the todo values.

unfinishedTasks = todos
    .filter(task => task.done == false)
    .map(task => task.todo);
