What you will learn

Read and write JavaScript you can explain, line by line|Make decisions and repeat work with conditions, loops and functions|Hold data in arrays and objects and reshape it with array methods|Control a web page with the DOM: content, styles, events and forms|Use modern scope, arrow functions, map, filter and find|Fetch data from an API with async and await, and save it with localStorage|Build a complete web application you can show to anyone

One concept, one day, one project. Thirty-two days that take you from "what even is JavaScript" to building real web applications, without rushing. We go in layers: make JavaScript think, make it reusable, make it control the page, make it modern, make it talk to the internet, then build real things. Every day explains one idea, shows it running, and has you build a small project with it.
