Fine-Tuning AirBnB's ESLint Config

ESLint was launched in June 2013 and has rapidly become the most popular JavaScript linter. It offers a number of advantages over other linters including fine-grained, configurable rules and plugin support. This flexibility can also be a weakness, however, as you can easily get lost in the multitude of options. For this reason, many developers have turned to a predefined rule set such as eslint-config-airbnb, based on the AirBnB JavaScript Style Guide. But why have such a flexible linter if we end up using a prepackaged configuration? Instead, let's take the predefined rule set and improve it with a few modifications. In the rest of this post, I describe my personal changes to the AirBnB rules and the reasoning behind each change.
