Description

Getting Started with JavaScript

Getting Started with JavaScript introduces beginners to core JavaScript concepts, practical browser scripting, and modern development workflows so you can confidently build interactive, accessible, and performant web applications from day one.

Course overview

JavaScript is the language of the web, powering everything from simple UI interactions to full-featured applications. This course demystifies JS syntax, data types, control flow, and functions, then guides you through working with the DOM, events, and browser APIs. You’ll learn how modules, tooling, and modern ES features fit together to create maintainable codebases, finishing with asynchronous programming patterns and integration tips for real projects.

What you will learn

• Language essentials: variables, types, operators, conditionals, loops, and functions.
• Modern ES features: let/const, arrow functions, template literals, destructuring, spread/rest, classes, and modules.
• DOM and events: querying elements, updating the UI, handling forms, and event delegation.
• Asynchronous JavaScript: callbacks, promises, async/await, and fetch for HTTP requests.
• Tooling and workflow: npm, package.json, dev servers, linters, and bundlers.
• Error handling and debugging: console tools, breakpoints, and defensive coding practices.
• Best practices: naming, immutability, accessibility considerations, and performance basics.

Who should enroll

• Beginners: new to programming or transitioning from HTML/CSS to interactive web development.
• Designers and marketers: looking to automate workflows and enhance landing pages.
• QA and support engineers: wanting to understand client-side behavior and reproduce issues.
• Students: preparing foundational skills for frameworks like React, Vue, or Angular.

Curriculum highlights

• Module 1: JS runtime model, strict mode, and scope (global, function, block).
• Module 2: Arrays, objects, Map/Set, JSON, and common data patterns.
• Module 3: DOM traversal, manipulation, CSS class toggles, and dynamic components.
• Module 4: Fetch API, REST calls, error states, loaders, and retry strategies.
• Module 5: Project setup, npm scripts, linting with ESLint, and prettier formatting.
• Capstone: Build a single-page UI that consumes an API, handles state, and persists data.
