Given the following code:

var fs = require("fs");

fs.watch('./test.txt', (event, filename) => {
    console.log(event, filename);
})

Running below in a directory where test.txt exists and gets deleted yields different results for event in 12.x vs 10.x:

• 12.x: change
• 10.x: rename

This basically renders node.js 12 incapable of detecting a file delete vs change when watching it.
