Question M1: I am wondering why the line Array.getChar(string, number) doesn't work. It seems like Apps Script doesn't load the Arrays library. I also have practically no experience with Java…

Google Apps Script is based on ECMAScript. Since the JavaScript programming language is also based on ECMAScript, many JavaScript functions will also work in Apps Script.

The code Array.getChar(string, number), however, is from the Java programming language, which is different from the JavaScript programming language.

In JavaScript (or Apps Script), to access the element at position i in an array arr, use arr[i].


var colors = ['red', 'blue', 'green'];
