Set Up and Learn Variables, Types, and Operators
1 weekOpen your browser's developer console (F12). Practice declaring variables with let and const, working with strings, numbers, booleans, and using arithmetic and comparison operators. Build a simple calculator in the console.

Master Control Flow and Functions
1-2 weeksWrite if/else logic and for/while loops. Create functions using both traditional and arrow syntax. Practice with real exercises: a grade calculator, FizzBuzz, or a temperature converter.
Learn Arrays and Objects
1-2 weeksMaster array methods (push, pop, map, filter, forEach) and object creation/access. Build a data-driven project like a shopping list or contact book using arrays of objects.
DOM Manipulation and Events
2-3 weeksConnect JavaScript to HTML. Use querySelector to select elements, modify text and styles, create new elements, and add event listeners. Build an interactive to-do list or a click counter.
Understand Asynchronous JavaScript
2-3 weeksLearn Promises, async/await, and the Fetch API. Practice fetching data from public APIs (like JSONPlaceholder) and displaying it on a web page. Handle loading states and errors.
Build a Complete Web Application
2-4 weeksCombine all skills into a full project: a weather app (Fetch API + DOM), a quiz game (events + logic + arrays), or a recipe finder (API integration + dynamic DOM). Focus on clean code, error handling, and user experience.
