Ever wondered how the search or replace button works? They are very useful commands. 

For beginners and professionals alike, we use these commands in our day-to-day work life, at least once a day. This is why I felt the need to build a course that could help you increase your knowledge and save time while working with strings or any sort of text.

The objective of this course is to help you get a strong grip on regular expressions, or in shorthand, regex. Instead of writing repetitive tasks, it mainly focuses on efficient searching in text files.

Regular Expressions for Programmers

Remember that there is more than one way to match a specific set of texts. Each method has its pros and cons that ultimately come down to efficiency, readability, and complexity for the current use case.

To master the skill, try to write all the possible ways to match the texts and eliminate the RegExs that are not precise. Learn how to combine different characters to parse complex texts.

You can use RegEx to parse data, validate, reformat, and much more. So,RegExs are a valuable skill!.
