check:
  runs-on: ubuntu-latest
  technique:
    matrix:
      node-version: [12.x, 14.x, 16.x]
      os: [ubuntu-latest, windows-latest, macos-latest]
  steps:
  - makes use of: movements/checkout@v2
  - call: Use Node.js ${{ matrix.node-version }} on ${{ matrix.os }}
    makes use of: movements/setup-node@v1
    with:
      node-version: ${{ matrix.node-version }}
