Go Fundamentals

Understand why Go exists, what problems it solves, and how to install and run your first Go program. Learn about Go's philosophy, compilation speed, static binaries, and the standard library.

Master Go's type system, variable declaration, constants, and zero values. Understand how Go stores data in memory and the implications for your code.

Learn how Go programs make decisions with if statements, switch cases, and loops. Master Go's approach to control structures and understand why Go only has one loop keyword.

Deep dive into Go's for loop - the only loop construct you need. Master range iterations, break, continue, and loop patterns for common programming tasks.

Understand Go's fixed-size arrays and dynamic slices. Learn how slices work under the hood, memory layout, capacity vs length, and slice operations.

Master Go's map type for key-value storage and understand string internals. Learn map operations, iteration, and string manipulation patterns.

Learn how to create custom types with structs and build complex types through composition. Understand embedded fields, struct tags, and Go's approach to code reuse without inheritance.

Deep dive into pointers for efficient memory management and channels for safe concurrent communication. Includes comprehensive memory diagrams and concurrency patterns.

Master functions, closures, anonymous functions, and methods. Understand value receivers vs pointer receivers and how methods enable polymorphism.

Master Go's core abstraction mechanism. Learn how interfaces enable polymorphism, testing, and flexible code design without inheritance. Understand implicit implementation and interface composition.

Learn Go's explicit error handling approach. Understand the error interface, creating custom errors, wrapping errors for context, and designing robust error handling strategies.

Understand Go's package system and module management. Learn how to organize code, manage dependencies, create reusable packages, and structure larger Go projects.

Master Go's built-in testing framework. Learn to write unit tests, table-driven tests, benchmarks, and examples. Understand Go's testing philosophy and best practices.
