Timers

delay(msec)
msec <number> The delay value in milliseconds.
Wait for msec milliseconds.
This function would block all the process for msec  milliseconds, so please use it carefully. it may block the Kameleon console and REPL. setTimeout, setInterval is strongly recommended instead of this function.
// Javascript example: Wait for 3 sec.
delay(3000); // delay 3 seconds.
millis()
Returns: <number> The current timestamp in milliseconds.
// Javascript example: Show the processing time of the function.
var startTime = millis(); // store start time.
for (var i = 1; i <= 10; i++)
  console.log ("Processing...", i * 10, "%");
var endTime = millis(); //store end time.
console.log ("Processing time is ", endTime - startTime, "ms.");
setTimeout(callback, timeout)
callback <function> The function which is called after timeout milliseconds
timeout <number> The timeout value in milliseconds.
Returns: <number> Timer id.
Set the timeout event which call the callback function after delay milliseconds.
// Javascript example: Show the message after 1 sec.
var timerId = setTimeout(function () {
  print('done.');
}, 1000); // 1sec timeout
setInterval(callback, interval)
callback <function> The function which is called at every interval milliseconds.
interval <number> The time interval value in milliseconds.
Returns: <number> Timer id.
Set the interval event which call the callback function everyinterval milliseconds.
// Javascript example: Print "tick" for every seconds
var timerId = setInterval(function () {
  print('tick');
}, 1000); // 1sec interval
// ...
clearInterval(timerId); // To stop printing "tick"
clearTimeout(id)
id <number> Timer id.
Clear timeout event which is set using setTimeout().
// Javascript example: Show the message after 1 sec.
var timerId = setTimeout(function () {
  print('done.');
}, 1000); // 1sec timeout
// ...
clearTimeout(timerId); // clear it after the timeout event.
clearInterval(id)
id <number> Timer id.
Clear interval event which is set using setInterval().
// Javascript example: Print "tick" for every seconds and clear it.
var timerId = setInterval(function () {
  print('tick');
}, 1000); // 1sec interval
// ...
clearInterval(timerId); // clear it to stop printing "tick"
