JavaScript Coding Specialist
A complete journey from your very first line of JavaScript to building interactive, browser-based programs. Across seven units you’ll master the language’s types and operators, control the flow of your programs, write reusable functions, model data with objects, and bring web pages to life through the DOM, the browser, and HTML forms — building toward an industry-recognized certification.
Welcome to the Course
This course takes you from absolute beginner to confident JavaScript programmer. You won’t just memorize syntax — you’ll learn to think like a developer: breaking problems down, modeling them in code, controlling program flow, and building pages that respond to the people using them.
Each unit ends with a hands-on project that puts your new skills to work, and everything aligns to the JavaScript Coding Specialist (JSCS) certification exam.
🗺 Course Roadmap
Here’s your path through the whole course. Each unit builds on the one before it — work through them in order for the smoothest journey.
📚 Units in This Course
Basics, Variables, Data Types & Literals
Get started with JavaScript and comments, then declare variables with var, let, and const; explore scope and hoisting; meet the primitive and object data types; and write array, object, string, and numeric literals.
Operators & Expressions
Work with assignment, arithmetic, comparison, logical, bitwise, string, and ternary operators; understand operator precedence; and build primary and left-hand-side expressions.
Control Flow, Loops & Error Handling
Make decisions with if…else and switch, repeat work with for, while, for…in, and for…of loops, and handle problems with throw and try…catch.
Functions
Define and call functions, understand function scope, pass and default parameters, and write concise arrow functions.
Working with Objects
Create objects and properties, enumerate and compare them, use inheritance, and put the built-in Number, Date, and Math objects to work.
The DOM & Browser Object Model
Build and navigate the DOM tree, handle HTML events, output to a page with innerHTML, locate and modify elements, and interact with the Browser Object Model.
Interact with HTML Forms
Retrieve and set form field values, validate input including NaN and string comparisons, and handle submission with onsubmit and the difference between post and get.
💡 What You’ll Be Able to Do
Go from Hello World to full programs — declaring variables with let and const, using operators, and structuring code the way professionals do.
Steer your programs with conditionals and loops, and keep them robust by catching and handling errors with try…catch.
Model problems with objects and properties, use inheritance, and tap into built-in objects like Number, Date, and Math to get real work done.
Use the DOM and Browser Object Model to find, change, and add elements, respond to events like onclick, and make web pages interactive.
Cover all 29 exam objectives across the seven units, building directly toward your JavaScript Coding Specialist certification.
