I have an Array that has users IDs some are only Alpha and
some are only Numeric. I want to search my array and remove the
Numeric values from the array so I only see the Alpha values when
displayed. I know I need to use Array.splice to remove the value
from the array but I am not sure how to identify if a value is a
number and not a name. The ID numbers are random and can range from
1 digit to 10 digits.
Is there any way to confirm if an Array value is a number?
