+ *
+ * Only change is we use console.warn instead of console.error,
+ * and do nothing when 'console' is not supported.
+ * This really simplifies the code.
+ * ---
+ * Similar to invariant but only logs a warning if the condition is not met.
+ * This can be used to log issues in development environments in critical
+ * paths. Removing the logging code for production environments will keep the
+ * same logic and follow the same code paths.
