JavaScript for Interactive Web
Learn browser programming through hands-on coding labs, logic challenges, DOM basics, and a final interactive webpage project.
Make the browser calculate and respond
JavaScript is a programming language used throughout the web. Variables store values, and console.log() lets you inspect output while building.
Use conditions to make choices
JavaScript uses if, else if, and else to make decisions. Comparison operators such as >= produce true or false results.
Work through a collection
An array stores multiple values. A loop can process each item without copying the same code again and again.
Turn repeated logic into functions
Functions let you name a reusable process. Parameters provide input, and return sends a result back.
Make a webpage respond to a user
The DOM is the browser’s representation of a webpage. JavaScript can select elements, change text, react to clicks, and build interactive experiences.
Build an interactive mini webpage
Create a small browser project such as a quiz, flashcard tool, interactive fact explorer, study timer interface, or mini game.
Project requirements
- Use variables and at least one array.
- Use a function.
- Respond to at least one user action.
- Update something visible on the page.
- Include accessible button labels and readable contrast.
- Explain one design decision and one bug you fixed.
