Best practices for TypeScript error handling in async functions

What are the recommended patterns for handling errors in async/await functions in TypeScript? Should I use try-catch everywhere or is there a better approach?
Great question! You can use the Array.map() method to transform each element. Here's a simple example: const numbers = [1, 2, 3, 4, 5]; const doubled = numbers.map(num => num * 2); console.log(doubled); // [2, 4, 6, 8, 10] The map() method creates a new array by applying a function to every element in the original array.

Another approach would be using forEach() if you need to perform side effects: const numbers = [1, 2, 3]; numbers.forEach(num => { console.log(num * 2); }); But remember, forEach() doesn't return a new array, while map() does. So choose based on your use case.
