For the type assertion section in 49:00, when you convert the type pageNum to a number, the type of is still a string when you do console.log(typeof numericPageNumber) and you can not perform numerical operations the way you would with a number, it still acts as a string. Am I missing something?

1:10:50 toString(16) is not about taking first 16 symbols, it's changing the base of the number to hexadecimal. -
In order to cut some excessive symbols after point, toFixed is used.

I watched this and crash course from traversy as refresher.
The traversy one is shorter but not as in depth as this one.
Especially on generic subject.
