TypeScript Recipes vs CapSee

Tap Run and the real output appears right under the code, along with any type errors. You know what the code does before it goes into your project. No Node.js or TypeScript to install, no IDE, no account. 360+ short examples, one task each. Over 90% run on Node.js 24 and pass strict TypeScript 7 type checking. You know what you need, but not the exact syntax: • How do I remove duplicates from an array? • How do I get an enum value from its name? • How do I merge two Maps? Each has a working example here. • 22 sections, including strings and dates, arrays and collections, classes and interfaces, enums, generics, arrow functions, async/await, exception handling, regular expressions, files, JSON, algorithms, and design patterns. • What changed from TypeScript 3.0 to 5.5, with before-and-after code: the unknown type, the ?. and ?? operators, template literal types, the satisfies operator, using declarations. • Reference, 120+ entries: keywords, operators, and utility types such as Partial, Pick, Record, and ReturnType. Tap a word in the code to look it up. • 200+ SQL queries: JOIN, GROUP BY, subqueries, window functions; more than half run on a practice database. • Search looks inside the code: type reduce to find every example that uses it. • Edit an example and run your version, or write your own: a type error shows up right away. • Works on iPhone, iPad, and Mac. • Everything except running code works offline. Free version: 190+ TypeScript examples and 120+ SQL queries, the full reference, and 12 runs and 12 edits a day (TypeScript and SQL runs share one limit). Full version: all examples and queries, unlimited edits and examples of your own, and up to 30 TypeScript and 80 SQL runs a day. One-time purchase, no subscription. Built by a developer for developers. The project behind it has been in active development since 2015.

Every snap, an answer. See something you don’t recognize? Open CapSee and take a photo. CapSee helps you identify animals, plants, food, objects, and everyday things — then explains what they are, what’s interesting about them, and how to say them in another language. CapSee is an AI photo encyclopedia and language-learning companion. It turns the real world around you into something you can understand, learn from, and come back to later. ◆ Key Features ◆ 【Snap to Identify】 Point your camera at an object and take a photo. CapSee detects the main subject and tells you what it is.

It explains features, uses, habits, background stories, and useful facts in a clear and friendly way. 【Learn Languages Naturally】 Each result includes words, pronunciation, and bilingual example sentences in your learning language.
