控制台不可用，因为代码在云中运行，而不是在浏览器中运行。相反，请使用GAS提供的记录器课程：

  Logger.log（playerArray [3]）
 

然后在IDE下的View> Logs ...下查看结果...

以下是一些关于使用GAS记录。

Apps脚本现在还提供堆栈驱动器日志记录。在查看 - 控制台日志下的脚本编辑器中查看这些日志。

I am very new to programming (have taken some of the JS courses on Codecademy). I am trying to create a simple script to determine, if given a spreadsheet with results from a poker game, who should pay whom. I opened up Google Apps Script, and wrote the following to get started:

function addplayerstoArray(numplayers) {

  var playerArray = [];

  for (i=0; i<numplayers; i++) {
    playerArray.push(i);
  }
}  

addplayerstoArray(7);

console.log(playerArray[3])

The idea is to create an array with the total number of players in it. When running the code, I thought it would print "3" to the console. But nothing happened. It said

"ReferenceError: "console" is not defined."

A) What do I not understand about how the Google Apps Script console works with respect to printing so that I can see if my code is accomplishing what I'd like?

B) Is it a problem with the code?

The console is not available because the code is running in the cloud, not in your browser. Instead, use the Logger class provided by GAS:

Logger.log(playerArray[3])

and then view the results in the IDE under View > Logs...

Here's some documentation on logging with GAS.

Edit: 2017-07-20 Apps script now also provides Stackdriver Logging. View these logs in the script editor under View - Console Logs.
