JavaScript is the backbone of modern web development. Mastering it requires understanding its quirks and best practices.
Modern JavaScript includes arrow functions, template literals, destructuring, and more. They make code cleaner and simpler.
Closures allow functions to remember their scope, useful for creating private variables and functions.
Use async and await for asynchronous operations instead of callbacks or raw promises.
Break your code into reusable modules. Use ES6 modules or CommonJS for better project structure.
Attach events to parent elements to handle multiple child elements efficiently.
Use closures, modules, or let/const to avoid polluting the global namespace.
Chrome DevTools, VSCode debugger, and console logging help identify issues quickly.
Batch DOM changes to reduce reflows and repaints or use virtual DOM frameworks.
Use try/catch for synchronous code and .catch() for promises to handle errors safely.
Stay updated with ECMAScript versions and popular frameworks to remain competitive.
