Go (Golang) comparisons: which one to use and why

The "X vs Y" questions people search and interviewers ask: goroutines vs threads, mutex vs channel, arrays vs slices, buffered vs unbuffered channels, and Go vs Java vs Python for first-job interviews.

  1. 01Goroutines vs threads: 8 differences that matter
    Why Go can run a hundred thousand goroutines when the same number of OS threads would sink your machine.
  2. 02Mutex vs channel in Go: when to use which
    Both make concurrent code safe. The Go team’s own advice is to use whichever is simpler.
  3. 03Arrays vs slices in Go: the differences, with examples
    An array is a fixed box of values. A slice is a window onto one. You will use slices 99% of the time.
  4. 04Buffered vs unbuffered channels in Go
    An unbuffered channel is a handshake. A buffered channel is a small queue.
  5. 05Go vs Java vs Python for your first job interviews: which should you pick?
    An honest comparison for campus hiring, new-grad interviews and your first backend job.
