TypeScript 5.5 introduces several new features designed to improve code safety and developer experience. Key updates include refined type-checking algorithms, inferred type predicates, improved control flow narrowing, and syntax checking for regular expressions. Additionally, new methods for Set operations such as union, intersection, difference, and symmetric difference have been added, enhancing code efficiency and readability. This version remains backward-compatible and addresses deprecated features from earlier updates.
