Join David Gassner for an in-depth discussion in this video How memory is allocated and managed, part of Up and Running with Go.
- As I've previously described,…Go has runtime that's statically linked…into each compiled application.…Along with any external packages that are declared…and imported in the application source code.…The runtime operates in its own background threads.…So like other managed languages like Java and C-Sharp,…memory is managed completely in the background.…And you don't have to explicitly allocate…or deallocate memory, it's all handled for you.…To understand how this is working,…and especially as you start getting into…more complex objects like maps,…which I'm going to describe in the next video,…it's important to understand the difference…between two built-in functions,…named make() and new().…
These functions can be used to declare instances…of maps, slices, and another type called channels…that I won't be describing in depth in this course.…The new() function allocates but doesn't initialize memory.…When you allocate a map for example,…using the new() function,…you'll get back a memory address…indicating the location of the map,…
