>- If the parameter cannot be converted to a number, then `NaN` is returned. 
> - If a date object is passed, then the number of seconds elapsed since January 1st, 1970 is returned. 
> - If more than one number is passed in a string separated by a space, then `NaN` is returned, unlike the `parseFloat()` function.
