Understand potential performance issues and techniques to address them
Requirements
Familiarity with jаvascript
Description
Hi, and welcome to the jаvascript Regular Expressions Course!
In just a couple of hours, you will gain precise and relevant information that you can immediately apply to your projects
I am Chandra Lingam, and I am your instructor.
Here are some typical uses of regular expression
You can implement a client-side check for input validation
For example, your app can guide the user to provide data in the correct format.
Here, the zip code is accepted in one of the two formats, and their format is specified using regex
As part of the zero-trust architecture, you need to validate input to your microservice
With jаvascript regex, you can verify and validate data payloads in your node js application
Regex also provides powerful text processing capabilities
Let's look at what you will learn in this course
The source code for this course is distributed using Github - so, you always have access to up-to-date code
As part of resources, you will get this high-quality cheat-sheet for regex language
And the supported operations
Besides, we will use an interactive regex tool to write and test patterns
Course outline
In the jаvascript Regex features section, you will get familiar with various regex methods, their purpose, and how to unit test your pattern
In the regex language section, you will learn how to write patterns - starting from the simplest of patterns
You will also learn to incorporate regex in your HTML input types for validation
Regex engine puts the onus on the developers, that is us, to write efficient patterns
In this section, you will gain knowledge of regular expression engine that will help you write optimal patterns
There are several exercises for you to apply your new skills
We then look at performance and how poorly written patterns can degrade exponentially
You will learn how to optimize the patterns and address performance issues
There are three hands-on projects in this course
You will learn how to apply the regex for three distinctly different data sets - unstructured log data, IoT sensor data, and parsing medical test data in HTML format
You will get prompt support through the course Q&A forum and private messaging.
I am looking forward to meeting you
Thank You!
Who this course is for:
jаvascript, Node Application Software Engineers and Developers
