Removed generator-exercises folder as it breaks jest-codemods run jest-codemods on .spec.js files, move generator-exercises back in Change references from Jasmine to Jest in main readme Update README with Jest specific language. Update some spec files with new syntax update tests, multiple exercises .gitignore: Added package-lock.json, package.json that were used when I ran code-blocks over the tests. Standardised function declaration calls across exercises fix typo in caesar.spec.js Ignoring package-lock.json, package.json Backtrack on .gitignore modification, add instructions to readme move files from testing repo to this repo Typo fixes, remove duplicate exercise folder Remove solution from non-solution branch Minor grammatical fixes added trailing semicolon to all function and module exports Fix words caught by search/replace action. remove doubled semicolon. Correct words caught by search/replace action. Add missing semicolon. Add .DS_Store to .gitignore multiple files: Added a blank line at the end of each file Ignore generator-exercise when linting exercise files Update exercise number of each exercise Update exercise number
