追加到数组（JavaScript）

Question

I'm trying to append to an array, with .push . It seems that this does not happen, and here is my code.

if(message.content.toLowerCase().startsWith('!startvote')) {
    let args = message.content.slice(1).trim().split(/ +/g);
    let command = args.shift().toLowerCase();
    let totalOptions = [];

    message.channel.send(`Starting vote. Use !vote1, to vote for the first option, !vote2 for the second, etc.`);
    message.channel.awaitMessages(msg => msg.content.startsWith('!vote1'), {time: 10000})
      .then(collected => message.channel.send(collected.size + ' users voted for \`option 1\`'))
      .then(collected => totalOptions.push({'optionOne': collected.size}))
      .catch(console.error);
    message.channel.awaitMessages(msg => msg.content.startsWith('!vote2'), {time: 10000})
      .then(collected => message.channel.send(collected.size + ' users voted for \`option 2\`'))
      .then(collected => totalOptions.push({'optionTwo': collected.size}))
      .catch(console.error);
  }

Whenever I try logging this somewhere else, the array returns empty.

Edit: here is the new code

message.channel.awaitMessages(msg => msg.content.startsWith('!vote1'), {time: 10000})
  .then(collected => message.channel.send(collected.size + ' users voted for \`option 1\`'))
  .then(collected => totalOptions.push({'optionOne': collected.size}))
  .then(console.log(totalOptions))
  .catch(console.error);
message.channel.awaitMessages(msg => msg.content.startsWith('!vote2'), {time: 10000})
  .then(collected => message.channel.send(collected.size + ' users voted for \`option 2\`'))
  .then(collected => totalOptions.push({'optionTwo': collected.size}))
  .then(console.log(totalOptions))
  .catch(console.error);

Because of asynchronous code, you may be outputting totalOptions befroe it's updated inside a then block.

try adding an extra then() block after the one where you push and console.log(totalOptions) in the new then().
