/*
In this challenge you will test your knowledge of arrays and array methods.
THE PROBLEM:
SPAM is major problem on the internet. Email applications like gMail do a lot of
work to identify spam and remove them from user's inbox.
YOUR CHALLENGE:
Complete the code below to correctly process a set of messages. The ones identified
as spam should be placed in a spam folder, otherwise they should be placed in the
inbox folder. You are provided with a spam detector function "isSpam" that will
return true if a message is spammy, and false otherwise.
Good luck!
*/
// This is your spam detection function.
// It will return true is a message is spam, and false otherwise
// DON'T UPDATE THE NEXT LINE
const isSpam = (message) => /money/.test(message.content)
// Accepts an array of messages and returns an object with two properties
// spam, and inbox.
// spam and inbox are array of spam and not spam messages respectively and are
// sorted
function processMessages (messages) {
// Hint: to sort the messages by time, you will use the sortFn below as your
// compare fuunction.
// the function accepts two message arguments (a and b) to be compared,
// and you will be comparing the time property i.e a.time and b.time
const sortFn = (a, b) => 0 // your code here (~ 1 line)
// use the isSpam function provided above to determine if a message is a spam
const inbox = [] // code your here.
const spam = [] // code your here.
// DON'T UPDATE THE LINE BELOW.
return {
inbox,
spam
}
}
// THIS IS HERE FOR YOUR TEST ONLY
const messages = [
{content: 'click here to make a lot of money', time: 10} ,
{content: 'hello are are you', time: 4} ,
{content: 'I just won some money, send your account number', time: 2},
{content: 'do you want to have launch', time: 11},
{content: 'we received your application', time: 3},
]
const {spam, inbox } = processMessages(messages)
// should print
// [ "I just won some money, send your account number",
// "click here to make a lot of money"]
console.log(spam.map(s => s.content))
// should print
// ["we received your application", "hello are are you",
// "do you want to have launch"]
