Otherwise, how do you represent `{ [k: number]: string }` in Zod?\n+\n+As it turns out, TypeScript's behavior surrounding `[k: number]` is a little unintuitive:\n+\n+```ts\n+const testMap: { [k: number]: string } = {\n+  1: 'one',\n+};\n+\n+for (const key in testMap) {\n+  console.log(`${key}: ${typeof key}`);\n+}\n+// prints: `1: string`\n+```\n+\n+As you can see, JavaScript automatically casts all object keys to strings under the hood. Since Zod is trying to bridge the gap between static and runtime types, it doesn't make sense to provide a way of creating a record schema with numerical keys, since there's no such thing as a numerical key in runtime JavaScript.\n+\n ## Arrays\n \n ```ts\n@@ -258,7 +333,7 @@ Unions are the basis for defining optional schemas.

install the latest version:\n\n```sh\nnpm install --save zod\n```\n\n```sh\nyarn add zod\n```\n\n### TypeScript versions\n\nZod 1.0.x is compatible with TypeScript 3.2+. Earlier versions contain bugs that will interfere there were known type inference bugs in TypeScript that will cause errors.\n\n# Usage\n\nZod is a validation library designed for optimal developer experience. It's a TypeScript-first schema declaration library with rigorous (and correct!) inferred types, incredible developer experience, and a few killer features missing from the existing libraries.\n\n- It takes advantage of TypeScript generic inference to statically infer the types of your schemas, eliminating the need to define static types and runtime validators sep\n\nFile: LICENSE\nMIT License\n\nCopyright (c) 2020 Colin McDonnell\n\nPermission is hereby granted, free of charge, to any person obtaining a copy\nof this software and associated documentation files (the \"Software\"), to deal\nin the Software without restriction, including without limitation the rights\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\ncopies of the Software, and to permit persons to whom the Software is\nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included in all\ncopies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
