Hey can anyone check out this script and tell me where it may have gone wrong? I keep getting a syntax error on line 17

Line 17: https.get(weatherURL, (res) => {

The purpose of the script is to periodically check weather.gov for new or updated severe weather alerts and to post those in my IRC room. Below is the whole script. I appreciate any help you can give.

const https = require("http.js");
const irc = require("irc.js");

const weatherURL = "https://api.weather.gov/alerts/active/zone/";

const client = new irc.Client("mybbs.synchro.net", "WeatherAlert", {
channels: ["#weather"],
});

client.addListener("message", function (from, to, message) {
if (message === "!weather") {
getWeatherAlerts(to);
}
});

function getWeatherAlerts(channel) {
https.get(weatherURL, (res) => {
let data = "";
res.on("data", (chunk) => {
data += chunk;
});
res.on("end", () => {
const alerts = JSON.parse(data).features;
if (alerts.length === 0) {
client.say(channel, "No severe weather alerts at this time.");
return;
}
alerts.forEach((alert) => {
client.say(channel, alert.properties.headline);
});
});
});
}

Still learning so please bear with me. I really appreciate the information.

It sounds like we're specifically saying that the "=>" is the problem or at least one of the syntax problems Am I right?

Right. => is often called a rocket operator (or "Arrow function expression") and is not supported in earlier JS implementations. Sorry, not "bullet operator" like I said.

That makes sense. I'll look into what I need to use in substitution for this "=>".

Much appreciated, DM.

You've got other problems beyond incompatible syntax.

In the code that you posted, you were doing something like:

http.get(url, res => {
let data = '';
res.on('data', d => data += d);
res.on('end', () => {
// do stuff with data
});
});

I suspect you took inspiration from a rather outdated node.js example. None of this will work here. In fact a vast amount of example JS code that you find online simply won't work here without significant alteration.

You want something like:

function getWeatherAlerts(channel) {
var data = http.Get(weatherURL);
var alerts = JSON.parse(data).features;
if (alerts.length < 1) {
client.say(channel, 'No severe weather alerts at this time.');
} else {
alerts.forEach(function (alert) {
client.say(channel, alert.properties.headline);
});
}
}

Use ircbot, it has a built in weather function.
