   • Outputs an informational message to the console.

console.info("This is an informational message.");

1. console.info()

   • Outputs an informational message to the console.

console.info("This is an informational message.");

console.warn("This is a warning message.");

4.console.error()

• Outputs an error message to the console.

console.error("This is an error message.");

5.console.table()

• Displays tabular data as a table.

const data = [
  { name: "John", age: 30 },
  { name: "Jane", age: 25 },
];
console.table(data);

1. console.group() / console.groupEnd()

• Groups log messages together.

console.group("Group 1");
console.log("Message 1");
console.log("Message 2");
console.groupEnd();

7.console.count()

• Outputs the number of times that console.count() has been called.

for (let i = 0; i < 3; i++) {
  console.count("Loop iteration");
}

8.console.time() / console.timeEnd()

1. • Measures the time it takes to execute a block of code.

console.time("Timer");
// Code to be timed
console.timeEnd("Timer");

function exampleFunction() {
  console.trace("Trace example");
}

exampleFunction();

10.console.clear()

• Clears the console.

These functions are just a subset of what the console object provides. Depending on your needs, you can choose the appropriate function to log information at different levels and formats.
