make vs new in Go: Differences and Best Practices
- In Go, make and new are both keywords for memory allocation, but they have distinct roles and usage scenarios.
- new allocates memory for a type and returns a pointer to that memory, initializing it to the zero value of the type.
- make initializes slices, maps, and channels, returning the initialized object itself without a pointer.
- Tips for using new: suitable for allocating memory for struct types and initializing them with zero values.
- Tips for using make: useful for initializing slices with specified capacity, maps with initial capacity, and buffered channels.
- Performance considerations: make incurs additional overhead due to type initialization, while new is more straightforward.
- Common misuse: Incorrectly using new for slices, maps, or channels can lead to runtime errors; make should be used for initialization.
- Choosing the appropriate method: Use new for simple allocations and make for initializing slices, maps, and channels with advanced requirements.
- Understanding the differences and choosing the right method can lead to more efficient and maintainable Go code.
