I have this code
bot.webex.memberships.list({roomId: bot.room.id})
.then((memberships) => {
for (const member of memberships.items) {
if (member.personId === bot.person.id) {
// Skip myself!
continue;
}
let names = (member.personDisplayName) ? member.personDisplayName :member.personEmail;
bot.say(`Hello ${member.personDisplayName`);
Which produce multiple output line by line Like this:
John Dou
Alfred Pennivor
Michel Lee
I need to create one array from this output, randomize this array and bot must say only one random name from array. Please note number of names maybe different
PS I try to use split but get 3 different arrays instead of one.
First, taking a random element from an array is explained in this question.
For only displaying a random element, which is NOT your own name, then this should work for you. Since memberships.items is already an array then we can directly extract a random element from it.
Example code:
bot.webex.memberships.list({roomId: bot.room.id})
.then((memberships) => {
let member
// take random member and repeat until it's not the current user.
do {
const items = memberships.items
// get random element
// https://stackoverflow.com/questions/5915096/get-a-random-item-from-a-javascript-array/5915122#5915122
member = items[Math.floor(Math.random()*items.length)];
} while(member.personId === bot.person.id);
bot.say(`Hello ${member.personDisplayName}`)
})
You can filter out the members that aren't you, and then map over that array of object to create a list of names. You then select a random name from that array.
bot
.webex
.memberships
.list({roomId: bot.room.id})
.then(logRandomName);
Here's a working example based off your code.
const bot = { person: { id: 4, name: 'Joe' } };
const memberships=[{personId:1,name:"Fozzie Bear"},{personId:2,name:"Carlos The Jackal"},{personId:3,name:"Bob From Accounting"},{personId:4,name:"Joe"},{personId:5,name:"Gunther"},{personId:6,name:"Ali"},{personId:7,name:"Renaldo"}];
function logRandomName(memberships) {
// First `filter` over the memberships array to
// to produce a new array that doesn't contain the
// member object that matches the bot.person.id
const names = memberships.filter(member => {
return member.personId !== bot.person.id;
// And then `map` over that array to return an
// array of names
}).map(member => member.name);
const rnd = Math.floor(Math.random() * names.length);
// Then pick a random name from the names array
console.log(`Hallo ${names[rnd]}`);
}
logRandomName(memberships);
