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

What about this one liner code ?

console.log([['dog', 'cat', ['chicken', 'bear']], [['mouse', 'horse'], 'lion']].join().split(','));

basically join will make comma separated string from nested array and using split you can get 1d array, nice ? bonus it'll work on all major browsers as well :)
