index.js

node_redis_commands.js

//with a previously create client

client.set('some-key','42',function(err) {
  if (err) { 
    throw err; /* in production, handle errors more gracefully */
  } else {
    client.get('some-key',function(err,value) {
      if (err) {
        throw err;
      } else {
        console.log(value);
      }
    }
  );
});

Issue: else part is not closed properly.

client.set('some-key','42',function(err) {
if (err) {
throw err; /* in production, handle errors more gracefully */
} else {
client.get('some-key',function(err,value) {
if (err) {
throw err;
} else {
console.log(value);
}
});
}
});

I have forked this example to make it works (missing closing bracket)
