Designing a pattern using a regular expression

/abc/ is a basic example of a regular expression profile, as are /ab*c/ and /Chapter (d+).d*/, both of which include both simple and special letters. Parentheses, used here as a reminder, are included in the final illustration. As mentioned in Using groups, the successful pattern match with this component is saved for further use.

Implementing Conventional Strategies

Direct matches are sought for in simple patterns, which are built from individual characters. The pattern /abc/, for instance, finds matches in sequences only when the specified character combinations appear in that precise order (all characters together and in that order). To illustrate, the strings "Hi, do you know your abcs?" and "The newest aircraft designs originated from slabcraft." would both be correct matches. The "abc" substring is the matching component in both circumstances. Even if the string "Grab crab" includes the substring "ab c," it does not include the precise substring "abc," thus it does not match.
