Maps Are References

In Go, maps are reference types, meaning when a map is assigned to a new variable or passed to a function, both variables point to the same underlying data. Any modifications made to one variable affect the original map.

Understanding Map References

When a map is assigned to another variable:

• Both variables share the same underlying data.
• Modifying one variable affects the other.
• The original and assigned map behave like aliases.
