React

What is React, really?

React is technically a JavaScript library, not a language, but it has become so dominant in frontend hiring that we have to include it. Facebook created it to handle their massive UI complexity, then open-sourced it. Today, Facebook, Instagram, Netflix, Airbnb, WhatsApp Web, and most modern web apps run on React.

Why learn it in 2026?

It is the most-asked-for skill in frontend job listings, by a huge margin. Even legacy PHP and WordPress projects are now adding React frontends. Bangalore frontend salaries with strong React skills start around 8 LPA and easily cross 30 LPA at senior levels.

What it looks like

// React counter
function Counter() {
    const [count, setCount] = useState(0);
    
    return (
        <button onClick={() => setCount(count + 1)}>
            Clicked {count} times
        </button>
    );
}
