Strings & Template Literals
Text, methods to reshape it, and expressions embedded inline.
Strings are immutable — every string method returns a new string rather than modifying the original. Template literals (backticks) allow multi-line text and `${expression}` interpolation, which is evaluated and converted to a string automatically.

Why?
toUpperCase() returns a brand new string. name itself never changes, because strings can't be mutated in place.
