Handling dates in JavaScript with Tempo

JavaScript's built-in Date constructor allows developers to perform date and time operations, despite its complexity in handling time zones, daylight saving time, and geographical date formatting. To address these challenges, various libraries have emerged, with Tempo being a notable option. Released in February 2024 by Justin Schroeder, Tempo is a lightweight TypeScript/JavaScript library that leverages the JavaScript Intl.DateTimeFormat constructor for locale-aware date formats and time zone handling, without creating its own custom date objects. Tempo's strengths include excellent timezone management, versatile parsing, and modification capabilities, a user-friendly API, and robust internationalization features. It avoids method chaining to enhance tree-shakability, ensuring only the necessary code is included in production builds. Compared to other libraries like Day.js, date-fns, and Luxon, Tempo stands out for its ease of use, efficient performance, and comprehensive date manipulation functionalities, making it suitable for projects requiring straightforward and effective date handling.
