JS Objects

Master the art of creating and structuring data in JavaScript.

object_factory.js1 / 3

📦

Object Creation Mode

Tutor: In JavaScript, an object is a collection of related data. We use curly braces {} to create an 'Object Literal'.

The Object Literal

The most common way to create an object is using the Object Literal syntax. It is a comma-separated list of name-value pairs wrapped in curly braces.

const car = {
brand: "Tesla",
year: 2024
};

Why Objects?

✅ Grouping: Keep related data together.
✅ Readability: Named keys make code self-documenting.
✅ Flexibility: Add or remove properties at runtime.

Object Creation Glossary

Key (Property Name): The unique identifier used to access a value.
