  • TypeScript, JSX and CSS supported without plugins
  • Runtime, bundler, test runner and package manager in one executable
  • Much faster startup and installs than the Node and npm equivalents
  • Plugin ecosystem is smaller than webpack's
  • Does not type-check TypeScript
  • Node compatibility is good but not complete; packages using deep internals can break
  • Younger than Node, so fewer production deployments to learn from
