+Logger logger = new DefaultLogger();
+
+// Create a default logger with the default joiner
+logger = new DefaultLogger();
+
+// Test out `error()`
+logger.error(["woah", "LEVELS!"], 69.420);
+
+// Test out `info()`
+logger.info(["woah", "LEVELS!"], 69.420);
+
+// Test out `warn()`
+logger.warn(["woah", "LEVELS!"], 69.420);
+
+// Test out `debug_()`
+logger.debug_(["woah", "LEVELS!"], 69.420);
