JavaScript

Estimated duration: 36 hours (8 modules, 31 lessons + 2 assignments + capstone)

What you will learn

• Run JavaScript in a page and the console; use let/const, primitive types, operators, template literals and strict equality
• Control flow with conditions, truthy/falsy values, logical and nullish operators, loops and try/catch
• Write functions (declarations, arrows, default and rest parameters), explain block scope and closures, and pass callbacks
• Process data with arrays and array methods (map, filter, reduce, find), objects, destructuring, spread and JSON
• Select, read, change, create and remove DOM elements and respond to events (incl. delegation and forms) accessibly and safely
• Store data with localStorage and handle asynchronous work: timers, promises, async/await, fetch with error handling
• Organise code with ES modules and classes, and debug with devtools
• Build and publish a small accessible, bilingual-ready interactive app

Who it is for: learners who can build static pages and want to make them interactive; future React/Node learners
