Description of changes
Fix an error in the https://unifiedjs.com/learn/guide/using-unified/#reporting section of the doc, where I believe the intention is to console.log the reporter results but it is wrongly added as console.error.
@wooorm when the file is read successfully why do we need to console it as error if there are none from the reporter?
Maybe I'm missing something here? I just looked at https://unifiedjs.com/explore/package/vfile-reporter/#use and everywhere it is console.error.
https://codesandbox.io/p/sandbox/fervent-brook-3vt3zr?file=/src/index.mjs:8,1 - here if you see the vfiles are valid but at the console it prints an error even though there are none
Ah! console.error does not mean that something is an error, and console.log does not mean something is good!
Particularly in Node and similar systems, console.error redirects to stderr, and console.log redirects to stdout. Two different pipes. Many shell tools will use this difference, stdout for the actual output file, and stderr for the diagnostics!
