[WaltEco]

Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• example/package.json
• example/yarn.lock

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

This major version upgrade introduces several significant dependency updates and new features, which may require configuration changes. Key changes include the introduction of Fast Refresh for hot-reloading, support for React 17's new JSX transform, and major version bumps for ESLint and Jest.

Highlights:

• ESLint 7: Upgraded from ESLint 6. This may introduce new linting rules. The EXTEND_ESLINT flag is no longer required for custom configurations.
• Jest 26: Upgraded from Jest 24. While often seamless, dependency conflicts with other libraries (like babel-jest) can occur and may require deleting node_modules and lockfiles to resolve.

Source: Create React App Changelog
Recommendation: After upgrading, delete node_modules and the lockfile (package-lock.json or yarn.lock), then run npm install or yarn install. Test your application thoroughly, paying close attention to the developer console for new ESLint warnings and running your test suite to ensure compatibility with Jest 26.
