Run GitHub Action on multiple environments

I want to run GitHub Actions on more than one environment, let's say on Windows and Linux. I managed to do it with Travis CI, but I could not find information about how to do it with GitHub Actions.

Has anyone tried it?

This is my nodejs.yml.

name: Node CI

on: [push]

jobs:
    build:
        runs-on: ubuntu-latest

        strategy:
            matrix:
                node-version: [12.x]

        steps:
            - uses: actions/checkout@v1
            - name: Use Node.js ${{ matrix.node-version }}
              uses: actions/setup-node@v1
              with:
                  node-version: ${{ matrix.node-version }}
            - name: npm install
              run: |
                  npm ci
            - name: prettier format check
              run: |
                  npm run prettier-check
            - name: lint format check
              run: |
                  npm run lint-check
            - name: build, and test
              run: |
                  npm run build
                  npm test --if-present
              env:
                  CI: true

You can use a matrix strategy:
