How to get the outputted results into a single array

Question

I am trying to complete the store manager challenge and I am close but struggling to put the final results into a single array.

This is my code:

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
for (element of prices) {

newPrice = element + increase;

console.log(newPrice)
}
}

How can I get it to console into a single array rather than a list that it is currently doing at the moment?

Answer 1

Log to console after the loop, not inside the loop.

for( let i = 0; i < prices.length; i++ )
{
prices[ i ] += increase;
}
console.log( prices );

Answer 2

Don't worry, we all stumble on something as we learn, it's just a part of the process 👌

Push the elements in an array

var arr = [];

for (element in prices) {

arr.push(newPrice);
}

Answer 4

Ahh Thank you. I should of thought of that, it seems so obvious now but hey I get it now.

Thanks a lot. I will hopefully remember this lesson for future cases.

Answer 5

ahh thanks. i should of thought of that, but now it is putting each element into its own separate array:

I have changed my code to use a for loop (namely as I wanted to try using one)

for (i = 0; i < 4; i++) {

let arr = [];
let result = prices[i] + increase;
arr.push(result);

console.log(arr);

}
}

I am now getting the following results:

[ 107.99 ]
[ 24.2 ]
[ 29 ]
[ 1035 ]

when I was expecting to get a single array like this:

[ 107.99, 24.2, 29, 1035 ]

Answer 6

When it comes to challenges, note carefully the task description. Be sure to check whether the task requires you to save <newPrice> to another array or to update <prices> directly. Is <increase> a value or percentage?

Answer 7

Right I am close but still no cigar as the saying goes.

I have managed to get the elements into a single array, however it console.log each iteration of prices array, when I need it to print the final iteration only.

[ 107.99, 15.2, 20, 1026 ]
[ 107.99, 24.2, 20, 1026 ]
[ 107.99, 24.2, 29, 1026 ]
[ 107.99, 24.2, 29, 1035 ]

My code:

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
for (i = [0]; i < 4; i++) {

prices[i] += increase;

console.log(prices);

}

}

I thought console.log(prices[3]) would achieve it but it just prints the fourth element of each array from above like so:

1026
1026
1026
1035
how can I get it to print just the entire array of the fourth iteration?
