Variables — var hoisting: undefined before declaration

var is hoisted with value undefined

When JavaScript sees a var declaration anywhere in a function, it "hoists" the declaration to the top of the function — but not the assignment. Accessing the variable before the assignment returns undefined.

Challenge: Write varHoisting() that:

1. Captures typeof hoisted before the declaration line
2. Declares var hoisted = 'later'
3. Returns the captured typeof result
