- Operators and Expressions:
- Arithmetic operators: +, -, *, /, %, etc.
- Comparison operators: ==, ===, !=, !==, >, <, >=, <=.
- Logical operators: &&, ||, !.
- Control Flow and Loops:
- Conditional statements: if, else if, else.

- Switch statements.
- Looping: for, while, do-while.
- Breaking out of loops: break, continue.
- Defining functions and function syntax.
- Parameters and arguments.
- Return values and the return statement.
- Function expressions and arrow functions.
- Function scope and closures.
- Creating and initializing arrays.
- Accessing array elements and array methods.
- Array iteration using loops and higher-order functions (e.g., forEach, map, filter).
- Working with objects: object notation, accessing properties, and methods.
- Introduction to the Document Object Model (DOM).
- Selecting elements with querySelector and querySelectorAll.
- Modifying element content, attributes, and styles.
- Creating new elements and appending them to the DOM.

- Understanding bundlers like Webpack and using them to bundle JavaScript files.
- Exploring popular libraries like jQuery for easier DOM manipulation.
- Understanding modern frontend frameworks like React, Vue.js, or Angular.
- Building projects of increasing complexity to apply knowledge and gain hands-on experience.
- Working on real-world projects to solve practical problems.
- Fetching data from APIs and integrating it into JavaScript applications.
- Understanding RESTful APIs and using fetch for HTTP requests.
- Learning Git basics: initializing repositories, committing changes, branching, and merging.
- Collaborating with others using GitHub or GitLab.
- Introduction to testing and its importance in software development.
- Setting up testing frameworks like Jest or Mocha and writing test suites.
- Exploring design patterns in JavaScript.
- Performance optimization techniques.
- Secure coding practices and handling security vulnerabilities.
- Introduction to Node.js and its use as a server-side runtime environment.
- Creating server applications with Node.js and Express.js.
