Is there an easy way to make nested array flat?

Question

That is to make this:

[ [\'dog\',\'cat\', [\'chicken\', \'bear\'] ],[\'mouse\',\'horse\'] ]

into:

[\'dog\',\'cat\',\'chicken\',\'

Answer 1

Grab underscore.js and use the flatten function.

_.flatten([ ['dog','cat', ['chicken', 'bear'] ],['mouse','horse'] ]);
