Let's head over to our exercise files and take a look at numeric types in JavaScript and Python. In JavaScript, we mostly see one double precision floating point type. Whether we simply define it as if it were an integer, like we see in line one or on line two, we will see that we get a floating point type and I will demonstrate that by logging the type of it to the console, as you can see on line four.
