JerseySTEM. Math Club. March 5, 2017. Introduction. Regular expressions are a powerful notation for specifying patterns in text strings.. Regular expressions are used routinely in such applications as text editors, language translators, and Internet packet processors.. 2. Regular Expressions vs. Finite Automata.
