what is odometer fr?

Odometer is a JavaScript and CSS library that animates numbers changing on a web page, making them tick upward or downward like the rolling digits on a physical odometer or a scoreboard. Instead of a number simply jumping from one value to another, Odometer makes the transition smooth and visible, which can make dashboards and live counters feel more polished and alive. The library was created and open-sourced by HubSpot, the marketing and sales software company. It handles the visual animation entirely through CSS transitions, with JavaScript handling the timing and state. The combination keeps the animation performance smooth in modern browsers. The README for this repository is minimal and links out to the project's documentation and demo site rather than including details directly. Based on the description and the code itself, Odometer is a front-end display component: you point it at a number on your page, and it takes care of the animated transition whenever that number changes. It is not a data fetching or business logic library, just a visual effect for numeric displays. The project is released as open source under HubSpot's open-source program.
