Go concurrency lets your program do many things at once. The main tools are goroutines and channels. Goroutines are lightweight threads that run functions. Channels let them communicate safely without shared memory.
Other important tools are sync primitives like mutexes and wait groups. Context helps you cancel work and set deadlines. These prevent race conditions and goroutine leaks.
Use this skill to build worker pools, pipelines, and graceful shutdowns. You will write concurrent Go code that is fast and correct. Debugging race conditions becomes much easier.
