When coding in JavaScript, we often use console.log()
to check what’s happening in our code. But did you know there are other, even more helpful, console methods? These can make debugging faster and more organized. Let’s explore five useful JavaScript console methods that can improve your debugging.
console.table()
console.table()
makes it easier to read and compare data.const users = [
{ id: 1, name: "Alice", age: 30 },
{ id: 2, name: "Bob", age: 25 },
{ id: 3, name: "Charlie", age: 35 }
];
console.table(users);
console.time()
and console.timeEnd()
console.time("loop");
for (let i = 0; i < 100000; i++) {
// Sample task
}
console.timeEnd("loop");
console.time()
and console.timeEnd()
, you’ll see exactly how long it took to run. You can even label it, so you can track multiple timers in one project.console.warn()
function oldFunction() {
console.warn("Warning: This function is outdated!");
}
oldFunction();
console.error()
try {
throw new Error("Oops, something went wrong!");
} catch (e) {
console.error(e);
}
console.group()
and console.groupEnd()
console.group("User Details");
console.log("Name: Alice");
console.log("Age: 30");
console.log("Location: New York");
console.groupEnd();
These five JavaScript console methods—console.table()
, console.time()
, console.warn()
, console.error()
, and console.group()
—are great tools to make debugging easier and faster. Instead of only relying on console.log()
, try these out! They’ll help you organize information, track issues, and improve how you analyze code behavior. Happy debugging!
