Harrison Malone - Loop Speeds

Found this pretty interesting. This is the straight up speed differences between Node.js and Go in a huge loop.

First up here's the Node.js loop.

let counter = 0
console.time("timer")
while (counter <= 1000000000) {
  counter += 1
}
console.timeEnd("timer")
// timer: 752.616ms

Here is the Go loop.

func main() {
  start := time.Now()
  counter := 0
  for counter <= 1000000000 {
    counter += 1
  }
  end := time.Now()
  fmt.Println(end.Sub(start))
  // 502.498873ms
}

Clearly Go is a lot faster. Will be interesting to see where these speed differences become really useful.
