smallestPowerOfTwo(1); // 1

Development
Setup
Assumes VS Code. Insignificant errors if not.
npm i
Testing
npm test
This will run the jest test suite.
Formatting
Ensure code is formatted with our style.
npm run format
This is generally unnecessary with "Format On Save" features of most editors. VS Code should work immediately.
REPL
Start a repl with functions smallestPowerOfTwo
loaded into the running context.
npm run repl
Versioning and Publishing
Just run any single npm
/yarn
version command.
# Any of these work. Other variations work too.
npm version major
yarn version
yarn version --minor
This will automatically run prettier and tests, ensure git worktree is clean, update version number, git commit and tag, build, publish, and git push to origin in a single command.
Build
Build ES3 and .d.ts
files from source.
Done automatically before publishing.
Useful for finding bugs in code before committing.
npm run build
