Is there a reason to ever use parseInt when parseFloat does the same thing?
parseFloat will convert an string like "100" into a number. Just wondering why we shouldn't use that all the time.

They do different things.
Sure, they both convert "100", but
parseFloat will also convert something like "33.3". On the other hand,
parseInt will enforce acceptance of only integer input, and it will also take a second argument that allows you to specify a conversion radix other than decimal.
What does the hex value "F00D" represent? will tell ya!

Hey there! I have found some discussions that cover the difference between using the two.
Here are also the docs for the different usages.
parseInt() has an extra parameter called "radix" which is describes as
radix: An integer between 2 and 36 that represents the radix (the base in mathematical numeral systems) of the above mentioned string. Specify 10 for the decimal numeral system commonly used by humans. Always specify this parameter to eliminate reader confusion and to guarantee predictable behavior. Different implementations produce different results when a radix is not specified, usually defaulting the value to 10.
I hope this helps!
parseInt will convert a string to an integer, something similar to the number 100, while parseFloat will convert a string to a float value, maybe something like 100.00
