| # This workflow will do a clean installation of node dependencies, cache/restore them, build the source code and run tests across different versions of node | |

| # There's no point in testing an outdated version of the code. GitHub only allows | |
| # a limited number of job runners to be active at the same time, so it's better to cancel | |
| # pointless jobs early so that more useful jobs can run sooner. | |
