find value(s) in [nested] arrays or objects
With these two functions, one being an Array prototype extension, you will be able to search through Arrays or Objects on values, nested Arrays or nested Objects on all nesting levels. Searching objects, you can define a key to confine the search to only that key. For both you can use the parameter 'nonbool' giving you the value you searched for (if found ofcourse) instead of a boolean indicating found/not found. Searching an Object containing Arrays, the Arrays will be searched too, and vice versa. inspired by: http://stackoverflow.com/questions/6315180/javascript-search-array-of-arrays/
