What are some examples of string matching in programming?

String matching is a technique used to find occurrences of a substring within a string. Examples include using functions like indexOf, includes, or regular expressions in languages like JavaScript, Python, and Java.

Can you explain how regular expressions work for string matching?

Regular expressions are patterns used to match character combinations in strings. They allow for complex searches, such as finding specific formats like email addresses or phone numbers.

What are some common use cases for string matching?

Common use cases include data validation, searching within text, parsing data, and implementing search functionalities in applications.

Are there any performance considerations with string matching?

Yes, performance can vary based on the algorithm used and the size of the strings. For large datasets, more efficient algorithms like Knuth-Morris-Pratt or Boyer-Moore may be preferred.
