Golang concurrency - Coggle Diagram

- - - - switch context to other process context

        main goroutine
        sub goroutine
        
        synchronization
        
        slow, but ...
        
        ... sometimes necessary
        
        channels
        
        buffered
        
        can have size
        
        not blocked until overbuffer
        
        usecase
        
        when two tasks are little slower or faster
        buffer can be helpful, because buffered chan
        does not block unless chan is full or empty
        
        unbuffered (default)
        
        if you are reading from chan, you are waiting until there is data coming,
        if you are writing to chan, you are waiting until this data is readed from chan
        
        mutex
        
        wait group
        
        can lead to (if you are dumb)
        
        deadlock
