It means handling an error.
When you write a program and run it, errors may occur.
To solve this, JavaScript has many error-handling techniques.
Using any of these techniques, you can identify and fix the error.
It ensures your program runs smoothly without stopping.
It also shows a message to the user, indicating where the error is, so the program does not stop suddenly.
Some of the error-handling techniques in JavaScript include:
- try…catch
- throw
- finally
- Error objects
- window.onerror
- Promise.catch()
- async/await with try…catch
