Regular Expressions (RegEx) Tutorial #15 - Email RegEx Pattern 

You make complex things turn into easy

I'm so grateful for founding this amazing tutorial, the videos are short so it isn't overwhelming at the sime time it has lots of videos explaining each part. Finally learned regex

Such a great and informative video which demystified what is regex and how to use it correctly and nicely. Bravo!

I'm loving everything about this series of tutorials :))))

Thank you so much. I Got headache when I saw RegExp tokens at first time but these videos helped me to understand how these token works

Best explanation ever. You have a talent, keep going. Thank you.

Very useful. Email addresses are very difficult to validate though, and the truth is it doesn’t matter how thorough you make it there’s no guarantee the user will type it in correctly anyway. Usually a confirm email box is added. I would let most characters through apart from those that have potential for malicious input and just check for an @ and dot character. But no way is the perfect way.

For many days I was thinking to learning Regular expression, here I found best one

this like magic you are wizard…. Finally after months and months I wrote my own RegEx the first time and can stop copying it without any understanding

This was a HUGE help, thank you

Thank you! Explained it in a easy way...

Great Tutorials🔥🔥 Keep up the good work 💯💯

Thank youuuuuuuuuuuuuuuuuu !!! This serie of videos was soooo helpful ! I'm grateful to you ❤

What a great tutorial, thanks a lot. I have been learning web dev myself wanting to switch careers and videos like yours help a lot. Many thanks.

Thanks a ton! You are a savior

Thank you very much Bro! you made everything easy love it

This was very helpful. Thank you for making this video!

I'm procrastinating to learn hard topics until you make the tuts

Great stuff, just what I need. Thanks

thankyou you are a great teacher

God bless all the Ninjas in the world ! specially The Net Ninja !!

no doubt, a great tutorial

Don't know if it is worth noting, but within a character set, the dot('.') doesn't need to be escaped

Plus (+) is also valid character before the @ symbol. I frequently use plus symbol when I'm sharing my email with the websites. It helps me to track down the spammers. That feature is natively supported by Gmail and many of the email provider.

Easy to understand

Best explanation!!

Thank you very much friend!!

Thank a lot sir

amazing..really necessary

awesome! thank you

This is great. How would you put it together, by not allowing the "submit" button not to work until all edits have been passed?

Dot does not to be escaped if inside the character class, I believe. Please correct me if I am wrong. Awesome tutorial by the way...

Tqs a lot.. May Allah bless u

Very good!

Hello, Thank you once again for the awesome tutorials, just want to point out, emails can also have underscores ( _ ) similar to dashes ( - ), I guess all one needs to do to add it is to add an '_' symbol within the group, right. Thanks.

Before first lecture : WTF! is this - /^([a-z\d\.-]+)@([a-z\d-]+)\.([a-z]{2,8})(\.[a-z]{2,8})?$/ After last lecture : Oh! this is so easy to understand. Thanks Net Ninja for this wonderful playlist on Regular Expressions .

How can i fix this error? "Uncaught TypeError: Cannot read property 'test' of undefined"

As being your appreciative, i think you're forgot the "_" symbol for the left of the "@" symbol. I think there is no more lack about email expression.

Hey I was just checking the codes in github and the js file is there but not the code.

what about confirm password ? How to validate that ?

what is the use of ^ (this symbol) ? why every pattern starts with ^ ?

You forgot to make it case insensitive. Even though emails are already case insensitite (meaning any email in all caps goes to the same address as its lowercase counterpart), capital letters shouldn't make the email address invalid.

When you search for this on c# and this shows up, cmon youtube -__-

5 dislikes from users who are debating the best RegEx for emails.

Not that this is a Dart/Flutter course, but there's a package in the pub called email_validator which precisely follows the specifications. There's a similar package for Perl called Mail::RFC822::Address that does the right thing again according to the standards. That module creates a regex up from smaller pieces, and for grins got expanded as www.ex-parrot.com/pdw/Mail-RFC822-Address.html . Yes, that page of text is the SMALLEST VALID REGEX for a legal email. If your handmade regex is any shorter than that, you will get false negatives. Specifically, the regex here fails on one of my addresses: fred&barney@stonehenge.com, and on one of my friend's addresses: *@qz.to. Yes, a solitary asterisk is a valid email localpart.

update@update this comes as valid email using above expression :(

validator.isEmail()

Thanks, for your playlist. But this RegEx wouldn't recognise my student e-mail: firstname.lastname@st.uni-domain.com . But this seams to be a speziell think because by some websites this e-mail causes problems.

The best Regex tutorials on RU-vid, thanks Master Ninja !! Thought underscore should be added as well /^([a-z\d\.-_]+)@([a-z\d-_]+)\.([a-z]{2,8})([\.a-z]{2,8})?$/

Thanks a lot sir
