Need help with discordjs bot

Hello, this is my first time attempting to create a discord bot.
I want the bot to send a random message to a channel at a set interval

The code i use is this :

client.on(‘ready’, () => {
var channelname = client.channels.find(channel => channel.id === ‘’)
var answers = [“a”, “b”, “c”, “d”, “e”]
var randomAnswer = answers[Math.floor(Math.random() * answers.length)]

console.log("The bot is logged in.")

setInterval(() => {
    channelname.send(randomAnswer)
}, 3000)

What i want it to do is pick a random message every X seconds from var answers and send it to specified channel.
What it ends up doing with this code is pick a random message once and then it repeats the same message every X seconds
How can i make it pick each time a different random message?

(i removed channel id from the code on purpose for this post)

var randomAnswer = answers[Math.floor(Math.random() * answers.length)]

put this inside the “setInterval”

Thank you very much, it worked
