$GOROOT and $GOPATH are both environment variables used in the Go programming environment, but they serve different purposes.
$GOROOT
$GOROOT is the environment variable that specifies the location of your Go installation. It points to the directory where the Go SDK is installed. This variable is typically set by default when you install Go, and you usually do not need to change it unless you are working with multiple versions of Go or have installed Go in a non-standard location. The $GOROOT variable is crucial for the Go tools to find the standard library and other runtime resources needed to compile and run Go programs[2][6][13].
$GOPATH
$GOPATH, on the other hand, is used to define the location of your workspace where your Go projects and their dependencies are stored. This is where the Go tools, such as the Go compiler and Go get, look for Go source files, packages, and binaries. Before the introduction of Go modules, $GOPATH was essential for managing project dependencies and organizing project structure. It typically includes three subdirectories: src (where your Go source files are kept), pkg (where package objects are stored), and bin (where executable files are placed after building Go programs)[1][2][6][13].
With the advent of Go modules in Go 1.11, the dependency on $GOPATH has been reduced for dependency management, as modules allow for versioning and package management outside the traditional...
