Which is the best approach to debugging?

Don't worry about it at all until after the program is written

Be sure the program will work perfectly before writing it.

Anticipate errors before they happen, and find and fix errors that happen.

Use an HTML encoder.

The best approach to debugging is to anticipate errors before they happen, and find and fix errors that do occur. This involves thorough testing, troubleshooting, and problem-solving throughout the development process. Waiting until after the program is written or assuming it will work perfectly without testing can lead to more difficult and time-consuming errors down the line. Using tools like an HTML encoder can also be helpful in preventing common coding mistakes.
