This video tutorial explores concurrency in Go, focusing on goroutines, channels, and the CSP model. It explains how Go's concurrency model differs from traditional thread-based models, highlighting the benefits of goroutines. The tutorial provides practical examples of launching goroutines, using wait groups for synchronization, and passing data to goroutines. It emphasizes separating concurrency logic from business logic and addresses common pitfalls when working with goroutines.

What is the primary concurrency model used in Go?

• Synchronized Blocks

• Global Interpreter Lock

• Communicating Sequential Processes (CSP)

• Threads

Which of the following is NOT a benefit of using goroutines over traditional threads?

• Managed by the operating system

• Ability to spawn thousands of goroutines

• Smaller stack sizes

• Faster creation time

In Go, what keyword is used to launch a new goroutine?

• run

• go

• launch

• start

Why is using sleep to wait for a goroutine to finish considered a bad practice?

• It is not precise and can lead to unexpected behavior

• It requires additional libraries

• It can cause deadlocks

• It only works with certain types of goroutines

What Go package is used to wait for goroutines to complete?

• wait

• goroutine

• sync

• time

How can you ensure that each goroutine receives a unique value in a loop?

• Use a global variable

• Use a mutex lock

• Pass the value as a parameter to the goroutine function

• Declare the variable inside the goroutine

What potential issue arises when goroutines share variables?

• Compilation errors

• Slower execution time

• Unexpected variable values due to concurrent access

• Increased memory usage
