Example: Logic and Math

() {
  score = 85
  ? (math.gt(score, 90)) {
    log.print("Grade: A")
  } : {
    log.print("Grade: B or lower")
  }
}

Example: Data Manipulation

() {
  fruits = ["apple", "banana"]
  arr.push(fruits, "cherry")
  
  arr.each(fruits, (item, i) {
    log.print(str.format("%1: %2", i, item))
  })
}

Example: Browser-Specific Tasks

This example uses the browser module, which is only available in the BrowserRunner.

() {
  msg = "Hello from the browser!"
  
  // This prints to the playground's internal output
  log.print(msg)
  
  // This prints to your browser's Developer Console (F12)
  browser.log(msg)
  
  // This triggers a native browser alert
  browser.alert(msg)
}
