Most modern infrastructure tooling is written in Go, largely because of its compiled performance and built-in concurrency. This quiz will test your understanding of how Go works, from its strict type system to its “Goroutine” model. Good luck! Answer key and explanations20 questions The quiz above draws 20 questions at random from these 30, so a second attempt will not be the same run. Everything in the pool is listed here. 1. What is a "Goroutine" in Go? AnswerA lightweight thread managed by the Go runtime 2. Which keyword is used to start a Goroutine? Answergo 3. What is a "Channel" in Go?

What is a "Method" in Go? AnswerA function with a defined receiver argument 26. What is the purpose of \`const\`? AnswerTo declare an immutable value at compile time 27. What is a "Deadlock" in Go Concurrency? AnswerA state where goroutines wait on each other 28. What is the "Blank Identifier" (\_)? AnswerAn identifier used to discard unwanted values 29. What is a "Map Literal"? AnswerA way to initialize a map with data directly 30. What is "Go Doc"?
