Guy, you're my favorite programmer youtuber.

Thanks for helping me in this session so goodly.
Greetings from Brazil 😀

'It replaced everything with blueberry. But do you realise whats now possible?'

Those who have finished this guy's amazing Regular Expressions tutorial,
Here is a good coding practice related to Regular Expressions from codewars!

It's always good to try to implement skills you just learned and try to use them in order to solve something!
Keep it up guys~

I used regex to seperate out half moves in chess to different capture groups from PGN files, to create a PGN viewer ( a chess game replayer) in JS 🙂 I love regex now, it saved me so much headache 😀

Write down Regular Expressions that can extract Strings 123.jpg and 432.png from

String axhdsjk123.jpg.jpg and hjhsd432.png.png

How to?

Here's a useful way to get a Date object easily using RegExp.

function getDate (str) {
const matcher = /d{1,2}-d{1,2}-d{4}/;
const match = matcher.exec(str);
return new Date(match[3], match[2], match[1]);
}

I've never seen a teacher as happy as you! thanks for making these videos.

It is possible to make a calculator with this regex:
/(d+)([-+*/%])(d+)/g

I've come back to watch this video so many times haha

there is chocolate and beer i guess

Kittens and kittens and kittens and kittens and kittens…. ? Kittens and rainbows and cupcakes ?

Very usefull, now I finally can say that I've learned about RegEx whit your tutorials series. Thank you very much teacher Danniel, regards from Mexico :-). YOU ARE THE BEST!!!

You're doing Gods work, Shiffman.

pls sir give me code for ana phora resolution in python

this is awesome ?

This video just triggered a Eureka moment in my brain. I'm 35 and just started learning coding 4 months ago and I think I've just turned a corner. Thank u man. I'm not sure what u did, but it's like a fog has just lifted off of javascript for me.

I would like to see you in strict mode

OMG! This is useful!

very useful tutorials….I've spent 4 hours trying to solve a problem, after watching your video I solved it within 2 minutes !!!

function imprim(){
var t5= ''
ctx.font = "Arial 14px"
positionY= 50
while( count< canvas.height/2){
ctx.fillText(t1,200,positionY)

positionY= positionY + 10
count = count +1}
function replace(t1){
var t5 = t1.replace(/t1/g,"php")
}

var t1= ' Hello javascript'
undefined
var t2= t1[3]
undefined
var t3 = t1.length
undefined
count=0
0
help me please

So the takeaway for me after this series of videos… RegEx is easy to write, yet difficult to read.

is it possible to say I want regex to capture a,b and c, but replace a with a certain section of a, replace be with a certian section of b, and replace c with a certain section of c… I was thinking that | would be used in the match part of the replace , but I havent found a decent example

how to store regular expression into sqlite?

You can also use replace() with a string instead of a regular expression

Thank God I found this :*

2 minutes into the video and I found my error. Now THAT'S a good video 😀 bye

that was an amazing tutorial, i didn't even noticed that i'm watching the last one.
in few hours i watched all your videos and i'm so thankful to learn from you.
greetings from Syria
you are the best.
