Regular expressions can help you more easily solve programming problems. They are an important tool in your coding toolbox. If you have dabbled with regular expressions or not even used them before, this course is for you. You will learn the syntax and participate in numerous examples and exercise to help you integrate regular expressions into your JavaScript code.

In Mastering Regular Expressions in JavaScript we focus on two main goals: Helping you learn regular expressions and how to construct them, and teaching you the powerful ways regular expressions can be used in JavaScript. If you work in the JavaScript language, this course will be most useful, but even if you work in another language you can use this course to learn about regular expressions as the syntax applies to many programming languages.

This course provides numerous opportunities to apply what is being taught. In fact one of the final sections is devoted to applying regular expressions, which basically presents different scenarios and then gives you a chance to solve them before  going through it with the instructor.

This course contains 9 sections, over 60 different lectures, over 5 hours of video tutorials, 5 exercises, 5 quizzes and 12 application lectures that will make sure you have what you need to use regular expressions in your JavaScript coding work.

If you are ready to master regular expressions, this course is for you.

At the conclusion of this section, you will be able to include different characters, escape characters, make use of meta-characters and use the wildcard in your regular expressions.
Understanding Metacharacters
Using the Wildcard

In the previous topic I mentioned that the wildcard character . represents any single character with the exception of some control characters like new line. Well in ECMAScript release 2018 a new flag was added to regular expressions in JavaScript. The new flag is the letter 's' and it called the dotAll Flag. This flag can be added to your regular expression if you would like the wildcard character to match all characters.

The dotAll flag can be included with other flags such as global 'g' or case insensitive 'i'.

Escaping Metacharacters
