What are some common error handling mistakes in TypeScript?

Some common mistakes include not using try-catch blocks effectively, ignoring promise rejections, and not defining custom error types.

Can you explain why ignoring promise rejections is a mistake?

Ignoring promise rejections can lead to unhandled promise rejections, which may crash your application or lead to silent failures.

What are custom error types and why should I use them?

Custom error types allow you to create specific error classes that can carry additional information, making error handling more precise.

How can I implement a try-catch block in TypeScript?

You can implement a try-catch block by wrapping your code in a try block and handling errors in the catch block, like this:

try {
  // code that may throw an error
} catch (error) {
  // handle the error
}
