What is @aws-crypto/supports-web-crypto?

The @aws-crypto/supports-web-crypto npm package is designed to check if the current runtime environment supports the Web Cryptography API. This is particularly useful for applications that need to perform cryptographic operations in environments where support for Web Crypto might vary, such as in different browsers or Node.js versions. By using this package, developers can ensure that their applications only attempt to use Web Crypto features when they are available, thereby avoiding potential errors in unsupported environments.
