- All var declarations are now const or let as per ES6 - All comma-separated lists / chained declarations are now one declaration per line - This is for clarity/readability but also made running the var-to-const/let switch smoother - ESLint rules updated to match How this was done: - npm install -g jscodeshift - git clone https://github.com/cpojer/js-codemod.git - git clone git@github.com:TryGhost/Ghost.git shallow-ghost - cd shallow-ghost - jscodeshift -t ../js-codemod/transforms/unchain-variables.js . -v=2 - jscodeshift -t ../js-codemod/transforms/no-vars.js . -v=2 - yarn - yarn test - yarn lint / fix various lint errors (almost all indent) by opening files and saving in vscode - grunt test-regression - sorted!
