TypeScript 3.8, released on February 20, 2020, introduces several significant updates to enhance the development experience, including type-only imports and exports, the export * as ns syntax, ES2020 private fields, top-level await, and JSDoc property modifiers. Type-only imports and exports provide more explicit syntax for handling types, particularly beneficial for module compilation scenarios. The export * as ns syntax simplifies module re-exports by bundling all exports under a single namespace, aligning with ECMAScript 2020 standards. ES2020 private fields introduce the # character to denote truly private class fields, offering stricter privacy than TypeScript's traditional private modifier, which is only enforced at compile-time. The addition of top-level await allows developers to use await expressions directly within modules, provided the target and module compiler options meet specific requirements. JSDoc property modifiers such as @public, @private, @protected, and @readonly enhance JavaScript code documentation and type-checking capabilities by specifying access levels and immutability for properties. These features, alongside other improvements and breaking changes, aim to streamline TypeScript development and align it more closely with modern JavaScript standards.
