To update Go, you will need to download the latest version from the official website (https://golang.org/) and then install it on your system. Here is a step-by-step guide on how to do this:
Check your current version of Go by running the following command in your terminal: go version
Visit the Go download page and choose the appropriate version for your system. You can choose either the stable release or the latest beta release.
Once the download is complete, navigate to the location where the installer file was downloaded and run the installer. On macOS, this will be a .pkg file, while on Windows, it will be an .msi file.
Follow the prompts to complete the installation.
Once the installation is complete, verify that the new version of Go has been installed by running the go version command again.
Note: If you installed Go using a package manager (e.g., Homebrew on macOS), you can use the package manager to update Go to the latest version. For example, to update Go using Homebrew, you can run the following command: brew upgrade go.
