Go Is for Multicore

Go supports multicore programming natively. You can see here all eight cores peaked out as the parallel code was distributed among the cores.

Support for Closures

Like most modern languages, Go includes support for closures, even though it's a strongly typed language.

Although the outer loop finished, the individual "goroutines" still had access to the outer loop's variables through closure. Each thread printed the value of the variable, "hello."

Working With Each Core

Go lets you specify the number of cores to use as you launch your "goroutines." Here we're using eight cores.

How it Works

Because we used eight cores, no cores were left for the outer loop, which, in turn, waited until the scheduler allowed it to move forward.

By adjusting the number of cores down to seven, one will be left for the outer thread.
