This book is for absolute beginners. Familarity with any other programming language is expected.

Following is a map of Chapter name and what topics they cover.

• Hello, World: Basic syntax, introduction to writing tests in Go.

• Integers: Documentation, example test/documentation.

• Iteration: For loops, benchmarks.

• Arrays and slices: Arrays, slices, len, test coverage.

• Structs, methods & interfaces: Structs, methods & interfaces and how are they used together.

• Pointers & errors: Pointers (copy by reference vs copy by value). Errors. nil.

• Maps: Maps (dictionaries), basic CRUD.

• Dependency Injection: Prerequisite to next chapter (mocking).

• Mocking: Test the behavior, not implementation. Don't rely on blocking resources, mimic them.

• Concurrency: go routines, channels, race contidions, . Make it work, make it right, make it fast.

• Select: Syntax sugar related to concurrency. Listen to multiple channels at once in a syntax similar to switch.

• Reflection: Go's internal datatypes.

• Sync: Supplement to concurrency. WaitGroups, Mutexes. A WaitGroup waits for a collection of goroutines to finish. A Mutex is a mutual exclusion lock. The zero value for a Mutex is an unlocked mutex.
