グラ単 - プログラミング英単語学習

The code looks like a "string of ciphers." That's simply because you're not yet familiar with the English words used.

For, return, iterate, async—when you first start learning programming, not understanding the meaning of these words suddenly reduces the amount of information you can glean from the code. Trying to interpret syntax, concepts, and English words simultaneously makes the first step incredibly difficult. Have you ever experienced that?

GraTan is a programming vocabulary learning app designed to lighten that burden. Learn steadily in Japanese on your iPhone. Start for free, and if needed, you can delve deeper with the monthly GraTan Pro subscription.

■ GraTan's "Three Stages"
1. First, "Get Used to It"—Words that looked like mere symbols transform into easily readable words.
2. "Understand the Meaning"—What exactly is "return"? What's the difference between "iterate" and "loop"? Don't leave things ambiguous.
3. "Applying it in the Field"—Vocabulary that you can read and understand forms the foundation of your ability to read and write code.

This two-pronged design is designed to reach not only beginners and newcomers, but also active engineers who want to re-inventory their vocabulary.

■ Choose the language and database you want to learn: 15 courses in total
v2.0 has been revamped with a "language thread learning model." By choosing the language or database you want to learn, you can follow a single path from introductory to advanced levels within that course.

• Programming Languages ​​(9): JavaScript / TypeScript / Java / Python / C# / VB.NET / VBA / Ruby / PHP
• Databases (5): PostgreSQL / MySQL / SQLite / T-SQL (SQL Server) / PL/SQL (Oracle)
• General Concepts Course (1): Basic concepts that are language-independent and should be learned before choosing a language. All 9 chapters, including version control (Git basics), CLI/shell, and testing/debugging concepts, are available for free.

Each course has four levels: Introductory, Beginner, Intermediate, and Advanced. All chapters in the Introductory level are free.

■ Daily "5 Questions of the Day"
Daily features 5 questions. Questions are drawn from multiple ongoing courses, allowing for comprehensive review of your chosen language. Questions are multiple-choice (English to Japanese, Japanese to English). You can practice both directions by recalling information from the choices. The more you continue, the more your continuous learning record accumulates.

■ Deepen Your Understanding Anytime with the Vocabulary List and Dictionary
You can always review words you've encountered in the vocabulary list. You can filter by status (not yet learned/in learning/mastered), course, 6-axis category, and 4 levels. You can search using partial matches in English, Japanese, and definitions, and sort by learning order, alphabetical order, and weakness order. Tapping a word opens a dictionary where you can view the definition, code examples, English example sentences, and related words on one screen. Code examples can be compared across multiple language tabs, allowing you to learn even the differences in notation between languages ​​for the same concept.


■ Test Your Skills to Assess Your Current Abilities
The skill test is a standalone feature that measures your current abilities. Results are displayed in five ranks—Beginner, Elementary, Intermediate, Advanced, and Master—and categorized using a radar with six axes. You can share your progress using a share card.

■ 45 Badges to Support the Enjoyment of Continuing
We've prepared 45 badges, covering learning progress, habits, skill tests, course completion, and even secret badges found in unexpected situations like Tanabata and New Year's. Upon achievement, a mascot celebrates with a full-screen animation.
