History and Evolution of JavaScript

What this section covers

This category walks you through JavaScript's origin story, its standardization as ECMAScript, and the major milestones that shaped modern web development. You'll learn the historical pressures and practical problems that led to JS's creation, and why those early design decisions still influence the language today.

Why this matters to a developer

Knowing how JavaScript evolved helps you make better design decisions. Historical context explains why the language has certain quirks, where compatibility constraints come from, and why newer features (like modules and async/await) were added the way they were. This knowledge prevents surprises and makes migrating or designing libraries easier.

How to use this section

• Start with Birth of JavaScript to see the original motivation and constraints.
• Read ECMAScript Standards to understand how the language is governed today.
