Example
console.log("Basic log", { user: "Alice" });
console.warn("Low memory warning");
console.error("Something failed");
console.table([{ name: "Alice", age: 30 }, { name: "Bob", age: 25 }]);
console.time("operation");
/* ... code ... */
console.timeEnd("operation"); Pro Tip
console.table() is excellent for visualizing arrays of objects during development.
