flatten(current) : current); }, []); }; If you only need simple flatten, this may works: var arr = [['object1', 'object2'],['object1'],['object1','object2','object3']]; var flatenned = arr.reduce(function(a,b){ return a.concat(b) }, []); For more complex flattening, Lodash has the flatten function, which maybe what you need: https://lodash.com/docs#flatten This is probably one of the better ways to flatten an object, by using a recursive flatten() function.
