Go fundamentals

Language foundations, errors, interfaces, defer, JSON, and everyday Go design.

What is Go? Understand packages, compilation, garbage collection, concurrency, HTTP tooling, tradeoffs, and a tested service handler.

Go Tools You Need for a Reliable Development Loop

Use essential Go tools to format, test, inspect, and build code with a repeatable local workflow that catches problems before review.

Understand Golang compilation and execution with go run, go build, and go install, then produce and verify a reusable application binary.

Learn a practical Golang file structure that starts small, separates commands from domain packages, and uses internal boundaries only when useful.

Build a Golang Hello World program, understand package main and func main, accept an argument, then run and compile it with Go 1.24.7.

Compare Golang IDE workflows and choose an editor by navigation, testing, debugging, remote work, and team needs instead of feature counts.

Learn Go interfaces, implicit satisfaction, consumer-owned contracts, nil traps, composition, and test doubles.

Encode and decode JSON safely in Go with struct tags, validation, unknown-field checks, and HTTP examples.

Download and install Golang on Windows, macOS, or Linux, verify the active toolchain, and avoid PATH and multiple-installation problems.

Learn Golang with a focused eight-week study plan built around tested programs, deliberate practice, projects, and production skills.

Why learn Golang? See where Go fits, what teams build with it, its tradeoffs, and a tested concurrency example before choosing it.
