The JavaScript Temporal API is set to enhance date and time handling by addressing numerous limitations of the old Date() API. User comments highlight its usability, especially for handling daylight saving time (DST) shifts and time zone differences, which historically trouble developers. The API incorporates features from robust time libraries, providing a clearer API to manage time complexities. However, it presents a learning curve as it differentiates between naive, instant, and zoned times. Developers express eagerness for its widespread adoption but also raise concerns about comparison methods, timezone data management, and the naming convention of the API.
