title: Looping through unknown number of array arguments
body: <p>I am trying to figure out how to loop through several array arguments passed. 
  For example: [1,2,3,4,5],[3,4,5],[5,6,7]
  If I pass it to a function, how would I have a function loop inside each argument (any number of arrays can be passed) ? </p>
  
  <p>I want to use a for loop here. </p>
