Description

Hi, and welcome to the JavaScript 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 JavaScript 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 JavaScript 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!
