Build this function by composing smaller functions:

     console.log(headline("Alice's ADVENTURES in WoNdErLaNd")); 
     // Alice's Adventures In Wonderland

Your goal is to produce an array with the IDs of the pending tasks for a given person, identified by name, which should match the responsible field. Solve this by using composition or pipelining:

     const allTasks = {
         date: "2017...
