"In our daily lives as programmers, we process text strings a lot. So I tried to work hard on text processing, namely the string class and regular expressions. Regular expressions are built into the language and are very tuned up for use"

Yukihiro Matsumoto is highlighting the importance of text processing in shows. He is specifically describing the string class and regular expressions, which are both necessary tools for programming. He notes that routine expressions are built into the language and are extremely enhanced for use. This recommends that regular expressions are an important part of programming and ought to be benefited from. By utilizing the string class and regular expressions, developers can make their code more effective and effective. Text processing is a basic part of programming and Matsumoto is encouraging programmers to put in the time to find out and understand these tools. He is emphasizing the value of text processing and how it can assist make programming simpler and more effective.
