BugFind the bug and fix the code

What it should do

countVotes(entries) adds up the votes of every entry. The votes arrive as text, like "3". Example: votes "3" and "4" → 7.

What happens instead

countVotes([{ votes: "3" }, { votes: "4" }]) returns "034".

function countVotes(entries) {
    let total = 0;
    for (const entry of entries) {
        total += entry.votes;
    }
    return total;
}

Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
