JavaScript Due for New Time, Date and Set Features Next Year

JavaScript's 2025 update will introduce several new features, including duplicate named capture groups for regular expressions and new set methods like union and intersection. Decorators, JSON modules, Promise.try, and potentially Temporal are also expected. These additions will enhance code efficiency, improve security, and address long-standing developer needs. The Temporal feature, while progressing, has faced implementation challenges requiring scope reductions. Overall, these updates aim to modernize JavaScript and improve its functionality across various aspects.
