Use the parseInt function with a Radix - solved but have a question

Tell us what’s happening:
I understand that I used 2 because the problem said to convert the binary number into an integer. When would I use any of the other numbers (2 - 36)? What would a problem look like that required the use of 19 or 36 (just random numbers other than 2) as the radix?

  **Your code so far**

function convertToInteger(str) {
return parseInt(str, 2)
}

console.log(convertToInteger("10011"));

8 and 16 are common (often used as more compact versions of binary numbers).
