Go compilers produce fast code fast. Typical builds take a fraction of a second yet the resulting programs run nearly as quickly as comparable C or C++ code.

< p > Go is type safe and memory safe. Go has pointers but no pointer arithmetic.
For random access, use slices, which know their limits.< / p >

2009-11-05 21:39:00 +00:00
< p >
Go promotes writing systems and servers as sets of lightweight
communicating processes, called goroutines, with strong support from the language.
Run thousands of goroutines if you want— and say good-bye to stack overflows.

< p >
Go has fast builds, clean syntax, garbage collection,
methods for any type, and run-time reflection.
It feels like a dynamic language but has the speed and safety of a static language.
It's a joy to use.
