 ### Types
-Go offers a rich collection of types, including numericas, booleans, strings, error, and the ability to create custom types. Strings are are a sequence of UTF-8 characters enclosed in double-quotes. Numerical types are the most versatile, with 8, 16, 32, and 64-bit variants for both signed (<code>int</code>) and unsigned (<code>uint</code>) integers.
