The TypeScript documentation is great. Have a look at it.

Linting

• eslint
• stylelint
• prettier - well, not strictly a linter, but close enough

Size

Great care has been taken to keep the library as light as possible. There could be a smaller net cost if you where already using one of the underlying dependencies.
