Not many people talk about Regular Expressions, even though they are incredibly useful for text manipulation and data validation.

They provide a powerful way to search, match, and replace patterns within strings.

In JavaScript, RegExp is an object that can be effectively employed to find and manipulate these patterns, whether you’re validating an email, formatting phone numbers, or parsing logs.

Regular Expressions can even extract specific data points from large chunks of text, making it easier to manage and analyze content.

For example, consider the simple expression let pattern = /[a-z]/g;—this pattern matches all lowercase letters in a given string, illustrating just one of the countless ways Regular Expressions can be utilized.

Mastering this tool can greatly enhance your ability to handle strings and data in JavaScript.
