I'll set up ESLint for your project. This tool helps catch and can also be used to enforce a consistent code style.
Having a linter continuously and automatically check every pull request ensures code quality stays solid. This can be enabled through GitHub and CI.
Having editor/IDE integration of ESLint shortens the feedback cycle. You'll catch most common errors while writing the code, instead of having to execute the code first. This short feedback loop results in greater developer happiness :-)
