Question

In index.js, build a function named writeCards() that accepts two arguments: an array of string names, and an event name. Create a for loop with a counter that starts at 0 and increments at the end of each loop. The for loop should stop once it has iterated over the length of the array.As with our previous wrapGifts() function, you will create a custom message for each name inside the loop. Unlike that example, however, instead of simply logging the messages to the console, you will collect them in a new array and return this array at the end of the function. (Refer back to the Array Methods lesson if you need a refresher on how we can add an element to an array.) The overall process should be:

create a new, empty array to hold the messages;

Answer 1

The writeCards() function iterates over an array of names and an event name, creating personalized messages that are stored in a new array which is returned at the end.

Step-by-step explanation:

The function writeCards() requires building a loop that iterates over an array of names, creating a custom message for each that includes the provided event name. The process of collecting these messages into a new array involves initializing an empty array and appending messages to it within the loop. Here's how you could implement this in JavaScript:

function writeCards(names, event) {
var messages = [];
for (var i = 0; i < names.length; i++) {
var message = “Thank you, ” + names[i] + “, for the wonderful ” + event + “ gift!”;
messages.push(message);
}
return messages;
}

This function takes two arguments: names (an array of strings) and event (a string representing an event name). Each iteration of the for loop generates a new message string specific to each name and the event, which is then added to the messages array using the push method. Once the loop completes, the function returns the array of personalized messages.
