Chapter Takeaways

• Go favors explicit over implicit constructs—errors are returned, not thrown
• Zero values provide safe defaults for all types
• Use := only when declaring new variables; use = for assignment
• Go uses composition over inheritance through structs and interfaces
• Interfaces are satisfied implicitly—no explicit declaration needed
• Pointers enable efficient data sharing without copying
• Slices are preferred over arrays for most use cases
• defer ensures cleanup code runs even when functions return early
