Add JS liniting about activities

[flopp]

npm install --no-save eslint installs eslint into the node_modules sub-directory.

node_modules/.bin/eslint web/app.js can then be used to check app.js.

This needs an .eslintrc.json config file, e.g.

{
    "env": {
        "browser": true,
        "es2020": true,
        "jquery": true
    },
    "extends": "eslint:recommended",
    "parserOptions": {
        "ecmaVersion": 11
    },
    "rules": {
    }
}

For the github actions, I would split it into another actions (not mixing python with JS)

Like this :

on: [push, pull_request]

jobs:
  tox:
    runs-on: ubuntu-latest
    strategy:
      max-parallel: 4
      matrix:
        python-version: [3.8]

    steps:
    - uses: actions/checkout@v2
    - name: Set up Python ${{ matrix.python-version }}
      uses: actions/setup-python@v2
      with:
        python-version: ${{ matrix.python-version }}
    - name: Install dependencies
      run: |
        python -m pip install --upgrade pip
        pip install tox
    - name: Test with tox
      run: tox -e format

  eslint:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Install modules
      run: yarn
    - name: Run ESLint
      run: eslint web --ext .js,.jsx,.ts,.tsx

Ah, ok. Makes sense.
