Previously, achieving this required manual grouping (using methods like
reduce) or relying on external libraries like Lodash.
However, with Object.groupBy(), you can achieve the same result in a more readable and concise manner.
Here are the key points:
- 💫 Functionality: group elements based on a specified string (object
keyor custom string).
- 💁 Browser Compatibility: available in modern browsers.
- 🛠️ TypeScript Support: included in v5.4-beta.
To explore and experiment with
Object.groupBy(), check out the following TypeScript playground to see the code in action.
I appreciate it if you would support me if have you enjoyed this post and found it useful, thank you in advance.
