Get better at practical skills by solving short challenges, understanding every mistake and seeing which skills grow stronger. XYZ starts with JavaScript, logic and English.
XYZ is in early development. JavaScript challenges are playable, including writing and debugging real code, and the playground is open; paths and review are still to come.
Every skill uses the same loop, so what you learn about practising carries over.
Each challenge is small: predict what code prints, finish a sentence, put steps in order or write a function.
Feedback explains why an answer is right or wrong, and names the specific mistake when it is a common one.
Challenges you missed come back later, so a mistake becomes practice instead of a dead end.
My Skills shows what you have practised and where you are improving, based only on what you solved.
Each area has its own skills. A challenge can practise more than one.
Read, write and debug code, starting with JavaScript.
JavaScript
Reason step by step, spot patterns and test whether a conclusion really follows.
Reasoning
Use language precisely, starting with English grammar, vocabulary and reading.
English
Later: Mathematics, Design & Digital Skills.
Different skills need different kinds of challenge. All of them will give feedback and an explanation.
XYZ is built in milestones. Each one ships something usable before the next starts.
Design system, navigation, both languages, both themes and the challenge model.
The challenge library and player for answer-based formats, with the first published JavaScript set.
A sandboxed JavaScript runner, code-writing and debugging challenges, and the playground.
Structured paths, and the first logic and English challenge sets.
Practice from your mistakes, and a transparent view of skill progress.
Sharing playground code, once a separate runner site and a read-first step protect whoever opens it.
Accessibility and performance audits, ecosystem listing and public release.
