Which of the following is true about goroutines in Go?

A. Goroutines are similar to threads in other programming languages.

B. Goroutines are executed sequentially.

C. Goroutines are heavyweight and consume a lot of memory.

D. Goroutines cannot communicate with each other.

Correct Answer is :

A. Goroutines are similar to threads in other programming languages.

Explanation

Goroutines are lightweight concurrent functions in Go that are managed by the Go runtime. They are similar to threads in other programming languages but are more efficient in terms of memory usage and context switching. Goroutines allow for concurrent execution of functions, enabling efficient utilization of multicore processors and enabling highly concurrent applications. Option B is incorrect because goroutines are executed concurrently, not sequentially. Option C is incorrect because goroutines are lightweight and consume minimal memory. Option D is incorrect because goroutines can communicate with each other using channels or other synchronization primitives.
