Go

Go is my go-to language for backend services, CLI tools, and DevOps tooling. The standard library covers most of what you need, the compiler is fast, and the concurrency model (goroutines + channels) makes it well suited for infrastructure-adjacent work.

Tooling

IDE: GoLand: JetBrains’ Go-specific IDE. Solid refactoring, built-in debugger, good test runner integration.

Formatting: gofmt / goimports: no debates about style, just run it.

Linting: golangci-lint: meta-linter that runs a configurable set of linters in one pass. Worth wiring into CI.

Testing

Testing is built into the standard library — go test ./... is all you need to get started. Table-driven tests are the idiomatic pattern for covering multiple cases cleanly.

func TestAdd(t *testing.T) {
 cases := []struct{ a, b, want int }{
 {1, 2, 3},
 {0, 0, 0},
 }
 for _, c := range cases {
 if got := Add(c.a, c.b); got != c.want {
 t.Errorf("Add(%d, %d) = %d, want %d", c.a, c.b, got, c.want)
 }
 }
}
