Describe the Problem

https://github.com/ethers-io/ethers.js/blob/9fd9d41d017a5e3b329aca47c79786e69cd40b99/package.json#L38-L39

Running Node.js v20.18.0, when you import a file that ends in .js, and the nearest package.json doesn't say type: "module" (and the package.json in ethers doesn't), it gets parsed as CommonJS.

So it just chokes with a SyntaxError when it sees ESM syntax.

Either ESM files have to end in .mjs, or "type" has to be added to package.json and all CommonJS files have to end in .cjs.
