What are regular expressions in the Go language?

Regular expressions in the Go language are a powerful tool used for matching and manipulating strings. They are a special text pattern used to describe specific formats or patterns within strings. In Go, regular expressions are supported by the regexp package. By using regular expressions, you can perform operations such as pattern matching, searching and replacing, and splitting strings. The syntax for regular expressions in Go is similar to that of other languages, but there are some small differences. Common operators in regular expressions include character classes, quantifiers, groups, and boundary matching. Regular expressions are widely used in text processing, data parsing, and syntax analysis scenarios.
