How does GoVet differ from golangci-lint?

GoVet is a static code analysis tool integrated into the Go ecosystem, focusing on identifying potential errors and suspicious constructs in the code. It checks for specific patterns that often lead to errors, such as incorrect format usage, inefficient constructs, etc.

golangci-lint is an aggregator of linters for Go, which combines many different tools (including GoVet) into a single run. It allows running multiple checks simultaneously, configuring them, filtering, and integrating into CI/CD.

Thus, GoVet is one of the tools, while golangci-lint is a comprehensive linter that can run GoVet and other linters together, providing a broader and more flexible code analysis.
