Which is better for string manipulation: string methods or regex?

It depends on the specific use case. String methods are generally faster for simple tasks, while regex is more powerful for complex patterns.

Can you give me an example where regex outperforms string methods?

Sure! If you need to validate an email address format, regex can handle that in a single line, while string methods would require multiple checks.

What about performance? Are there benchmarks comparing the two?

Yes, benchmarks show that for simple operations, string methods are usually faster. However, regex can be optimized for specific patterns.

Are there any downsides to using regex?

Yes, regex can be harder to read and maintain, and it may lead to performance issues if not used carefully, especially with complex patterns.
