+/**
+ * ts-node transpiler plugin
+ *
+ * This plugin hooks into ts-node so that Sucrase can handle all TS-to-JS
+ * conversion while ts-node handles the ESM loader, require hook, REPL
+ * integration, etc. ts-node automatically discovers the relevant tsconfig file,
+ * so the main logic in this integration is translating tsconfig options to the
+ * corresponding Sucrase options.
+ *
+ * Any tsconfig options relevant to Sucrase are translated, but some config
+ * options outside the scope of Sucrase are ignored. For example, we assume the
+ * isolatedModules option, and we ignore target because Sucrase doesn't provide
+ * JS syntax downleveling (at least not in a way that is useful for Node).
+ *
+ * One notable caveat is that importsNotUsedAsValues and preserveValueImports
+ * are ignored right now, since they are deprecated and don't have exact Sucrase
+ * equivalents. To preserve imports and exports, use verbatimModuleSyntax.
