let isThisDeno = typeof Deno !== "undefined";

let curves = getCurves();
for (let curve of curves) {

  // Exchange and generate the secret...
  let aliceSecret = alice.computeSecret(bobKey);
  let bobSecret = bob.computeSecret(aliceKey);

  // OK
  console.log('aliceECDHSecret   ', aliceSecret.toString('hex'));
  console.log('bobECDHSecret     ', bobSecret.toString('hex'));
  console.log('publicKeySize     ', aliceKey.length);
  if (!isThisDeno)
    console.log('privateKeySize    ', alice.getPrivateKey().length);
  console.log('sharedSecretSize  ', aliceSecret.length);
  console.log("");
}

nit:

-let isThisDeno = typeof Deno !== undefined;
+let isThisDeno = typeof Deno !== "undefined";

Thanks @kt3k !
