Validation](https://github.com/moltar/typescript-runtime-type-benchmarks#validation)\n\nThese packages are capable of validating the data for type correctness.\n\nE.g. if `string` was expected, but a `number` was provided, the validator should fail.\n\n### Interface\n\n[Permalink: Interface](https://github.com/moltar/typescript-runtime-type-benchmarks#interface)\n\nIt has a validator function or method that returns a valid type casted value or throws.\n\n```\nconst data: any = {}\n\n// `res` is now type casted to the right type\nconst res = isValid(data)\n```\n\nOr it has a type guard function that in a truthy block type casts the value.\n\n```\nconst data: any = {}\n\nfunction isMyDataValid(data: any) {\n // isValidGuard is the type guard function provided by the package\n if (isValidGuard(data)) {\n // data here is \"guarded\" and therefore inferred to be of the right type\n return data\n }\n\n throw new Error('Invalid!')\n}\n\n// `res` is now type casted to the right type\nconst res = isMyDataValid(data)\n```\n\n## Local Development\n\n[Permalink: Local Development](https://github.com/moltar/typescript-runtime-type-benchmarks#local-development)\n\n###

cases](https://github.com/moltar/typescript-runtime-type-benchmarks#test-cases)\n\n- **Safe Parsing**\n - Checks the input object against a schema and returns it.\n - Raises an error if the input object does not conform to the schema (e.g., a type mismatch or missing attribute).\n - Removes any extra keys in the input object that are not defined in the schema.\n- **Strict Parsing**\n - Checks the input object against a schema and returns it.\n - Raises an error if the input object does not conform to the schema (e.g., a type mismatch or missing attribute).\n - Raises an error if the input object contains extra keys.\n- **Loose Assertion**\n - Checks the input object against a schema.\n - Raises an exception if the input object does not match the schema.\n - Allows extra keys without raising errors.\n - Returns true if data is valid.\n- **Strict Assertion**\n - Checks the input object against a schema.\n - Raises an exception if the input object does not match the schema.\n - Raises an error if the input object or any nested input objects contain extra keys.\n - Returns true if data is valid.\n\n## Contributors\n\n[Permalink:

But the real question isn’t which one is better — it’s whether you can still afford to ignore TypeScript._**\n\n**JavaScript built the modern web. And TypeScript is gradually stealing it.** If you were still unreliable to switch in 2026, the ecosystem has begun making the decision for you.\n\nThis is not a post on the language war An uncompromising view of what this looks like on both sides and what it really costs to keep stuck on plain JS in 2019.\n\nPress enter or click to view image in full size\n\n\n\n## The Numbers Don’t Lie\n\nTypeScript placed third overall in the programming languages used last year in the 2024 Stack Overflow Developer Survey — ahead of Java, but behind Python and JavaScript. Even more telling, it continues to be one of the most loved languages from year-to-year.\n\nMore importantly, in 2026, most new React, Next. js, and for full-stack Node projects it’s created scaffolded with TypeScript out of the box. So you are asked upfront when you create your app using `create-next-app`.
