如何在 Javascript 中为 discord 机器人制作随机发生器？

Question

I'm a beginner in coding and I'm trying to learn to code a discord bot that messages a random generated things, like lets say I'm doing an advice command, what I want it to do is to pick 1 out of 10 advice tips randomly. Hopefully anyone understands, thank you.

You should first create an array for the randomly generated outcomes. If we're talking about advice as you mentioned, you would want to type:

const advices = [
  'eat melon',
  'eat melon every day',
  'eat melon a lot',
  'melon is healthy',
  'melon is very epic'
];

Once you've created your array, you can generate a random value from your array by typing:

// get a random number based on the array's length
var randomIndex = Math.floor(Math.random() * advices.length);
// creates the random output of your array
var randomElement = advices[randomIndex];

From there, you can simply use randomElement as the randomly generated value from your array.

message.reply(`Here is a good advice: ${randomElement}`);
