The author creates a project to gather statistics about the top most starred projects on Github or the most downloaded packages on NPM.

1. 9-27% of JS/TS projects declare themselves to be ES Modules
2. Less than 6% of JS/TS files declare that they are ES Modules via the .mjs, .cjs or .mts file extensions.

Some ideas:

1. kill .mjs, .cjs and .mts should be replaced by the type="module" in package.json. Let's stick to .js, .jsx, .ts and .tsx
2. Make type="module" the default and warns when the type is not set to module.
3. We should upgrade the most common libraries used by the community to ES Modules
4. The NPM registry can require an explicit module field on new packages, making it clear when a package intentionally uses CommonJS.
5. NodeJS can officially drop support for require and module.exports in a future version, creating a bit more pressure to migrate.
