     24    * Syntax:
     25    *
     26    *     math.size(x)
     27    *
     28    * Examples:
     29    *
     30    *     math.size(2.3)                  // returns []
     31    *     math.size('hello world')        // returns [11]
     32    *
     33    *     const A = [[1, 2, 3], [4, 5, 6]]
     34    *     math.size(A)                    // returns [2, 3]
     35    *     math.size(math.range(1,6))      // returns [5]
