Is Blob arrayBuffer() method being polyfilled?

I can't find Blob.arrayBuffer() in the doc, I'm not sure if it is handled by core-js 🤔

About the Blob: arrayBuffer() method:

• Add simpler reading methods to Blob interface. w3c/FileAPI#117
• https://developer.mozilla.org/en-US/docs/Web/API/Blob/arrayBuffer
• https://caniuse.com/mdn-api_blob_arraybuffer
• Rule proposal: prefer-blob-reading-methods sindresorhus/eslint-plugin-unicorn#1269

Hi. Thanks for the issue.

In my vision, it's out of the current scope of core-js - now it covers ECMAScript, ECMAScript proposals, and some cross-platform Web APIs that are maximally closer to ECMAScript.

We can't polyfill Blob everywhere since it's tightly integrated with and / or represents platform-specific APIs. We can't polyfill Blob.arrayBuffer since IIRC we have no ways that will work everywhere (however, I could be mistaken, because I did not delve into this issue).

Theoretically, in the future can be added a Blob.arrayBuffer polyfill that will add it in cases where it's possible, however there are many APIs closer to ECMAScript.

Thank @zloirock for the detailed answer 👍

Do you know any equivalent to core-js for the the Web API that includes Blob polyfills?

For such web polyfills, you could take a look at core-web - however, I see a polyfill for Blob, but not for .arrayBuffer.
