days=['m', 't'];
days.map(function (a){paste(a)});

function paste(day) {
      alert(day)
}

This works but aga's is better. ( shorter).

However - notice cross platform issue http://jsbin.com/axaluq/42?q=array%20map

You need to pass your paste function to map, not invoke it: 

var days = ['m', 't'];
days.map(paste);

function paste(day) {
  alert(day)
}

map function will iterate through the days array and invoke the function you passed in it on every object of the days.
