For printing debug statements, do not use the browser console for output. This tab will act like your development terminal/console.
To see compilation errors (e.g. syntax errors), you must interact with the application to trigger the output.
See below for an example of printing output in each of our supported languages:
Clojure
(println "debug")
C# / .NET
using System;
...
Console.WriteLine("debug");
Go
import ( "fmt" )
...
fmt.Println("debug")
Java
System.out.print("debug");
Node
console.log("debug");
PHP
echo "debug";
Python
print("debug")
Ruby
puts "debug"
