Course Description

Regular expressions are an essential part of problem solving in computer science. They can be tricky to learn if you don't approach the topic right.

In this course, we hope to break down the regular expressions into manageable parts so you can learn them fast and retain the concepts much longer.

This course will be useful for both Javascript programmers and programmers of other programming languages because we focus on the core concepts of regular expressions before teaching you how to apply them in Javascript.

You'll also learn the sheer power of regular expressions, used in combination with the powerhouse that is the Javascript language. Add the latest ECMAScript updates to the mix, and you end up with something that is unparalleled in the other languages.

Every concept is taught through a wealth of over-the-shoulder examples so you understand the concepts better.

Why should you choose our course? 

1. We like to be thorough in our teaching. You'll find everything you need to start creating complicated regular expression patterns. You won't have to look anywhere else. 

2. We strongly advocate learning by doing, rather than just listening or reading. Our lectures are filled with a wealth of examples that explain every concept clearly. 

3. If you follow along with our examples in our over-the-shoulder trainings, and create our examples with us, you'll have a thorough understanding of what regular expressions are, and how they work in Javascript. You'll be able to confidently add this as a skill in your resume. 

4. We prefer creating fun projects to explain the concepts and to keep things interesting as well. You'll learn how to apply the concepts you learn in the course in the real world projects and examples.

So, what are you waiting for? Enroll now and start creating complicated, yet accurate regex patterns that can be used in real world pattern matching scenarios in no time at all!
