Object Collection in JavaScript

Objects in JavaScript are collections of key-value pairs. They are versatile and can be used to represent a wide range of data structures. Objects are often used for creating dictionaries, maps, and records.

let person = {
    name: "Maria",
    age: 28,
    city: "New York"
console.log(; // Accessing a property

Keys are always strings (or Symbols, introduced in ES6). When you use non-string values as keys in an object, JavaScript implicitly converts them to strings.

Objects are generally used for a simple dictionary-like structure with string keys.
