13 languages and SQL queries
Free · In-App Purchases
A reference of everyday operations in 17 programming languages
• Python, JavaScript, TypeScript, Java, Kotlin, Swift, Objective-C, C#, C++, Golang, Rust, PHP, Ruby, Clojure, Delphi, 1C and SQL.
The construct is on the tip of your tongue, but the exact syntax slips away:
• How do you sort an array with the language's own tools?
• How do you run a task on a background thread?
• How do you insert a substring at the right place in a string?
The app answers with a ready-made example, and all that is left is to adjust it to your task.
• Over 3600 ready-to-use examples (snippets), free: strings, arrays, collections, files, networking, multithreading, design patterns.
• SQL in a section of its own, with a practice database: JOIN, GROUP BY, ORDER BY, subqueries, data types.
• Run examples and see the result right in the app: most examples and every SQL query are runnable. Running requires an internet connection.
• Add your own examples, up to five per language.
• Prepare for interviews and exams on examples you can trust.
• Examples are selected from professional literature and specialist resources, and every one of them has been verified by running it.
• All content works offline.
Limits of the free version: running, editing and keyword lookup, 12 times a day each; copying code, 5 times in all.
The full version opens all 6500 examples and lifts the limits. One purchase, no subscription.
Made by a developer for developers.
