fire idea !

Checking the 1s test ???

1. Execution Timed Out (12000 ms)

2. Console [result] deeply equal [Test]
   Completed in 10950 ms (min 6711ms)

   .... 
   if ( steps > 1000000 ) {
      // test: 30 000 000
      console.log(result); 
      return [];
   }
   return result;
   

return false/False

or

throw "Error"

Discription:
F(n) being the smallest one such as F(n) * F(n+1) > prod.

F(n) ... 55, 89, 144 ...
prod === 5895

55 * 89 = 4895 < 5895
89 * 144 = 12816 > 5895 ===> [55,144,false]

cool! match vs split

perfectly!
