About this course
Start from zero and learn JavaScript the way working developers use it: variables, conditionals, loops, functions, arrays, objects, the DOM, events and fetching live data — all by writing and running real code in your browser. By the end you will build a small interactive web feature and share a live link, the exact kind of proof that lands web-developer and remote coding jobs paid in naira and dollars.
HTML is the bones, CSS is the looks, and JavaScript is the brain — it is what makes a web page actually DO things. Learn it and you hold the key to interactive web and remote dev jobs.
