Regular Expressions Lab

In this lab, you will explore JavaScript's Regular Expression syntax and create a few different regular expressions. Regular expressions are useful when you need to search, match, or replace parts of a text or validate specific patterns within a string. JavaScript offers two ways to create regular expressions: Regular Expression Literal (/pattern/flags) and RegExp constructor (new RegExp(pattern, flags)).

You will learn to create and test regex by writing JavaScript code. By the end of this lab, you'll have hands-on experience with regex literals, RegExp constructors, and various regex flags.

Prerequisites

• Basic understanding of JavaScript syntax
• Familiarity with string manipulation in JavaScript

Objectives

1. Create and use Regular Expression Literals
2. Instantiate RegExp objects using the RegExp constructor
3. Understand and use regex flags to modify match behavior
