Core Mindsets for JavaScript Developers

1. Embrace Asynchronicity

JavaScript lives in the browser and handles events. Understand that operations don't always happen in order. Master callbacks, Promises, and async/await.

2. The DOM is Your Canvas

Your main job in frontend JS is manipulating the DOM. Treat it as a dynamic tree that you can change to create interactive user experiences.

3. Flexibility is a Double-Edged Sword

JS is a dynamic and flexible language, which is powerful but can also lead to errors. Be disciplined with data types and use tools like linters.

4. Stay Current, but Master the Fundamentals

The JS ecosystem changes fast. Focus on mastering the core language features first, as they are the stable foundation everything is built on.
