Go Pointers: Memory Addresses, Not Math
Go pointers are street addresses for data. Instead of copying a large struct, you pass its memory address. This lets functions modify the original value and is critical for performance.
Go pointers are like street addresses for data in memory. Instead of copying a whole house (a large struct) every time you pass it to a function, you just pass its address. This allows the function to directly modify the original data and avoids expensive copies. They are essential for methods on types and for performance with large data. The main footgun for C/C++ developers is assuming pointer arithmetic is possible; Go explicitly forbids it to improve safety.
