How is this computed?

round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10) — computed 2026-09-02. Adoption (stars, forks) is never an input.

Propel was a JavaScript library for differentiable programming, providing tensor operations and automatic differentiation for scientific computing and deep learning in the browser and Node.js. It was abandoned in 2018 after the release of TensorFlow.js, with the team recommending TFJS instead.

Use cases

  • run neural network training in the browser
  • automatic differentiation in JavaScript
  • tensor math with GPU acceleration in Node.js
  • scientific computing in JavaScript
  • build and train ML models without Python

When to choose

  • you need a historical reference for JS autograd implementations
  • you are researching pre-TensorFlow.js JavaScript ML libraries

When to avoid

  • you want an actively maintained deep learning library for JavaScript (use TensorFlow.js)
  • you need production ML training or inference today
  • you expect bug fixes, releases, or community support
