Instead of setting ESLint environment to "node" globally, set it on per-directory basis using separate .eslintrc.json files: Directory Environment ----------------------- bin node lib commonjs spec jasmine It was impossible to use this approach for the "benchmark" directory which contains a mix of files used in various environments. For benchmark/run, the environment is set inline. For the other files, as well as spec/helpers.js, the globals are declared manually (it is impossible to express how these files are used just by a list of environments). Fixes #408.
