Practical TypeScript Tips

TypeScript has become standard in modern frontend development. Here are some practical tips I've accumulated. ## 1. Leverage Type Inference TypeScript has strong type inference capabilities: ```typescript const name = 'hello' // automatically inferred as string const numbers = [1, 2, 3] // automatically inferred as number[] ``` ## 2. Union Types and Type Guards Union types with type guards produce very safe code: ```typescript type Result = Success | Error function handleResult(result: Result) { if ('data' in result) { console.log(result.data) } } ``` ## 3. The Power of Generics Generics allow us to write reusable, type-safe functions. ## 4. Utility Types TypeScript has many built-in utility types like Partial, Required, Pick, Omit, etc. Mastering these tips will make your TypeScript code more concise and type-safe.
