Don’t memorize the solution. Discover it.

Learn programming by fixing real errors — one hint at a time

Arabic library for debugging errors with progressive hints — each hint reveals a new layer until you solve it yourself.

LIVE_PREVIEW — php // SYNTAX

<?php
$name = "Ahmed"
echo "مرحبا $name";

LVL_01 › terminal

› راجع السطر السابق لموضع Parse error؛ الخطأ قد يكون رمزاً ناقصاً في نهايته.

How it works

Pick an error

Browse by language & difficulty — each error has real code and clear description

Try to solve

Read the code, think hard, open a hint only when you need it

Open hints gradually

Each click reveals one level — green (easy) → yellow → red (hard)

From the library

Same cards as the library — real content from DB

js RUNTIME Hard

عدم معالجة خطأ JSON.parse

تمرير نص غير صالح JSON لـ JSON.parse يرمي SyntaxError ويوقف التنفيذ إذا لم يُلتقط.

python SYNTAX Easy

نسيان النقطتين بعد if/for/def

بنية Python تعتمد على : لبدء الكتلة. نسيانها يسبب SyntaxError: expected ':' وتوقف المفسر ق...

python LOGIC Easy

استخدام = بدلاً من == في شرط

العامل = للإسناد لا يصلح داخل if، Python يطلق SyntaxError: invalid syntax لأنه يتوقع مقارن...

js LOGIC Hard

الاستنساخ العميق بـ JSON وتأثيره على التاريخ

JSON.stringify يحول التاريخ لنص ويفقد الدوال وundefined، فالنسخة لا تحافظ على الأنواع.

Why DebugLibrary is different

01 — HINTS

Learn progressively — not by memorization

An article gives you the answer, Stack Overflow gives a quick fix. Here each hint reveals one layer — you think, try, then reveal the next. You build debugging intuition instead of copy-paste.

02 — ARABIC

Arabic content with technical depth

PHP, JS and Python errors explained in Arabic with real code and practical context — not literal translation, but explanation for Arab developers.

03 — EDITOR

Feels like a code editor

Dark background, Fira Code, and typing hints like VS Code — you feel you are fixing a real bug, not reading a lesson.

FAQ

No. Errors are leveled easy/medium/hard. Start with easy (green) and progress — each level builds on the previous.

Yes, 100% free. Register, solve, earn points (10 per solve − 2 per hint) with no limits.

Currently PHP, JavaScript and Python — with code examples for each and growing.

Each error has levels. One click reveals one level with typing effect — LVL_01 green, LVL_02 yellow, LVL_03 red. Fewer hints = more points.

Yes, your dashboard shows points, top categories, and recent attempts with direct links to retry.
