Goroutine： Goroutine 是一个函数或方法，它与您程序中存在的任何其他 Goroutines 相关联地独立并同时执行。或者换句话说，Go 语言中每个并发执行的活动都称为 Goroutines。
线程：进程是操作系统的一部分，负责执行应用程序。在您的系统上执行的每个程序都是一个进程，为了在应用程序内部运行代码，进程使用称为线程的术语。线程是一个轻量级的进程，换句话说，线程是一个执行程序下代码的单元。所以每个程序都有逻辑，一个线程负责执行这个逻辑。
以下是 Goroutine 和 Thread 之间的一些区别：
| Goroutine | Thread |
|---|---|
| Goroutines are managed by the go runtime. | Operating system threads are managed by kernal. |
| Goroutine are not hardware dependent. | Threads are hardware dependent. |
| Goroutines have easy communication medium known as channel. | Thread doesnot have easy communication medium. |
| Due to the presence of channel one goroutine can communicate with other goroutine with low latency. | Due to lack of easy communication medium inter-threads communicate takes place with high latency. |
| Goroutine doesnot have ID because go doesnot have Thread Local Storage. | Threads have their own unique ID because they have Thread Local Storage. |
| Goroutines are cheaper than threads. | The cost of threads are higher than goroutine. |
| They are cooperatively scheduled. | They are preemptively scheduled. |
| They have fasted startup time than threads. | They have slow startup time than goroutines. |
| Goroutine has growable segmented stacks. | Threads doesnot have growable segmented stacks. |
