How to install dependencies in github actions and use them in other jobs?

Question

GitHub

For example, there is the most basic Create React App project. This project has one Workflows file:

name: Check Pull Request

on: [pull_request]

jobs:
  installDeps:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/[email protected]
      - uses: actions/[email protected]
        with:
          node-version: 14

      - run: npm ci

  launchTests:
    needs: deps
    runs-on: ubuntu-latest
    steps:
      - uses: actions/[email protected]
      - run: npm test

How can dependencies be used to run launchTests installed in jobs - installDeps?
