mapFunc.js

var passengers = [ ["Thomas", "Meeks"],
                   ["Gregg", "Pollack"],
                   ["Christine", "Wong"],
                   ["Dan", "McGaw"] ];

var modifiedNames = passengers.map(function(cell){ return cell[0] + ' ' + cell[1];});

console.log(modifiedNames);

//This will log: ["Thomas Meeks", "Gregg Pollack", "Christine Wong", "Dan McGaw"]
