9,393 Pointsconverting input before comparing.
One of the things I learned from java is before comparing 2 things like integers, if one's not an integer you need to convert via the parseInt() method. For instance, when asking a user for input, it stores it as a string, then you need to convert it to an integer, then compare the values. Otherwise you'll get an error while compiling because the data types don't match.
Would this still be the best practice for numbers in javascript instead of using == to compare 2 types that aren't the same data type?

Also, the typeof method is your friend when trying to figure out a particular data type.
