What are console.table's main functionalities?

Display Array of Objects

This feature allows you to display an array of objects in a table format. Each object represents a row, and the keys of the objects represent the columns.

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

Display Array of Arrays

This feature allows you to display an array of arrays in a table format. Each inner array represents a row, and the elements of the inner arrays represent the columns.

const cTable = require('console.table');
const data = [
  ['John', 30],
  ['Jane', 25]
];
console.table(data);

Display Object of Objects

This feature allows you to display an object of objects in a table format. Each key-value pair in the outer object represents a row, and the keys of the inner objects represent the columns.

const cTable = require('console.table');
const data = {
  person1: { name: 'John', age: 30 },
  person2: { name: 'Jane', age: 25 }
};
console.table(data);
