Code Recipes Pro

Code examples for 13 programming languages and SQL, organized by task. Look up

how something is done in a language you don't use every day and get a working

snippet — not a wall of theory.

About 5,000 examples in 26 sections that follow how developers think:

collections, control flow, generics, concurrency, regular expressions, files,

databases, serialization, algorithms, design patterns, reflection, LINQ.

LANGUAGES

Swift, Kotlin, Java, Objective-C, C#, C++, Go, Rust, Python, JavaScript,

TypeScript, PHP, Ruby, and SQL.

WHERE IT HELPS

• Switching languages. The topic tree is identical everywhere: find the pattern

you know in one language, see how it is written in another.

• Interviews and exams. The tree covers the questions that come up most often.

• Syntax you touch twice a year. Date formatting, regex groups, JSON

serialization, thread pools, file I/O — a couple of taps instead of a search

session.

WHAT'S INSIDE

• Examples with the expected output shown inline, so you can check the result

without running them.

• A separate SQL section: 201 queries with result tables and short explanations.

• Search by topic name or by a fragment of code.

• Works fully offline. No account, no sign-in.

• Favorites for the snippets you come back to.

• Optional links to online playgrounds when you want to run something.

• Light, dark or system theme; adjustable font and size; optional line numbers.

• On iPad: topic list and code side by side.

• Interface and content in 15 languages.

In development since 2015.
