Computer Science and Software Engineering Theory with Briana - JavaScript Lingo: Regular Expressions

RegExp (Regular Expressions) in JavaScript RegExp is not formatted like anything else in JS, and can have a steep learning curve. RegExp can also be an incredibly useful and efficient tool. Using RegExp, you can match, replace, search, and split a string, one of the more difficult types of values to manipulate. Like with all of the other videos, we won't get into the nitty gritty, but I want to show you a few examples of where RegExp is useful. If you wanted to create a registration page that verified passwords contained at least a number and a capital letter, you could use RegExp. If you wanted to ensure that dates entered in a page were all valid dates in the future, you could use RegExp. While there are limitless ways to use RegExp, many of them include validating information that users input. ❤️ Support for this channel comes from our friends at Scrimba – the coding platform that's reinvented interactive learning: https://scrimba.com/freecodecamp
