Evaluating the similarity between a Guild ID and a matching string

Currently, I am in the process of creating a bot with a unique feature - a config command that enables users to customize specific functionalities within their servers. This customization is facilitated through a straightforward JSON file named config.json, which stores the server ID along with various boolean variables representing the features:

{
  "servers": [
    {
      "id": INSERT_ID,
      "delete": true
    },
    {
      "id": INSERT_ID,
      "delete": true
    },
    {
      "id": INSERT_ID,
      "delete": false
    }
  ]
}

The main objective is for the bot to search through this list when the config command is executed and locate the server that matches the ID of the message sender's server. To achieve this functionality, I have devised the following code snippet:

let data = fs.readFileSync(__dirname + "/config.json");
let config = JSON.parse(data);

let found = false;
for(let server of config.servers) {
    if (server.id === message.guild.id.toString()) {
        found = true;
        if (server.delete) {
            server.delete = false;
            message.reply("`Message Delete` has been toggled to `False`");
        } else {
            server.delete = true;
            message.reply("`Message Delete` has been toggled to `True`");
        }
    }
}
if (!found) {
    message.reply("I couldn't find this server in the database!");
}

let newData = JSON.stringify(config)
fs.writeFileSync(__dirname + "/config.jsom", newData);

Interestingly, upon using console.log on message.guild.id, it accurately displays a number matching the strings stored within my JSON file. However, the IF statement

if (server.id === message.guild.id)
consistently returns false, leaving me puzzled as to the underlying cause.

Although your question may have already been addressed in the comments, I wanted to offer an alternative approach to achieving the same outcome (while also providing a comprehensive answer).

Instead of relying on a for/of loop to locate the item that meets your specified criteria (matching guild IDs), you can streamline the process by utilizing the built-in find method of arrays. Here is how you can implement this in your code:

let found = config.servers.find(server => server.id == message.guild.id);

if (found) {
    if (found.delete) {
        found.delete = false;
        message.reply("`Message Delete` has been toggled to `False`");
    } else {
        found.delete = true;
        message.reply("`Message Delete` has been toggled to `True`");
    }
}
else {
    message.reply("I couldn't find this server in the database!");
}

In my opinion, this approach offers a cleaner solution compared to using a for/of loop, as it reduces the need for nested conditionals and loops. This code essentially achieves the same result as your current implementation (albeit likely employing a for/of loop internally). Additionally, remember that when comparing values in JavaScript, it’s important to differentiate between == and ===, and there's no necessity to convert message.guild.id to a string before using ==.
