I modified your code as below to flush out the error:

const process = require('child_process')
const child = process.spawn('ping 8.8.8.8 -t') // instead of process.exec
setTimeout(() => {
    console.log(child.kill(2)) // --> false == failed
}, 10000);

child.on('error', (code, signal) => {
    console.log(`${code}`) // --> Error: spawn ping 8.8.8.8 -t ENOENT
});

The ping command requires an argument after the -t ( as per terminal: ping: option requires an argument -- t
