Basic Exampletypescript
1import { trySync, tryAsync, isTryError } from 'try-error';

3// Synchronous operations
4const result = trySync(() => JSON.parse(jsonString));
5if (isTryError(result)) {
6 console.error('Parse failed:', result.message);
7} else {
8 console.log('Parsed data:', result);
9}
10
11// Asynchronous operations
12const asyncResult = await tryAsync(() => fetch('/api/data'));
13if (isTryError(asyncResult)) {
14 console.error('Fetch failed:', asyncResult.message);
15} else {
16 const data = await asyncResult.json();
