It is fun and educating. Thank you )

Quite educative and exciting. What is createP?

6 years later this video still comes in handy

My idea is have large completely normal looking document. Each space after each word would represent either a “1” or a “zero “ depending whether there are one or two spaces there thus hiding your binary program in the document.

Thank u

dx=[0,2.5,0,-2.5];
dy=[2.5,0,-2.5,0];
dir=0;
count=0;
function setup() {
createCanvas(400, 600);
x=width*0.3
y=height*0.75
oldx=x;
oldy=y;
background(0);
a="FX"
for(i=0;i<12;i++){
a=a.replace( /F/g,"F+T");
a=a.replace(/f/g,"F-f");
a=a.replace(/T/g,"f");}}
function draw() {
if(a.charAt(count)=="+"){
dir++
if(dir==4){dir=0}}
if(a.charAt(count)=="-"){
dir--
if(dir==-1){dir=3}}
oldx=x;
oldy=y;
x+=dx[dir];
y+=dy[dir];
if(a.charAt(count)!="X"){
stroke(sin(count/50)*255,0,255-sin(count/50)*255);
line(x,y,oldx,oldy);
count++}}

hi can you tell me regular expression for how to replace <p> tag with <br> tag

This guy made it look easy. Yesssssssiiiiirrrrrskiiiii

Thanks Buddy! You prevented me of converting 8k lines of code by myself.

Year 2021, ES6 has Rest parameters. It's preferred over the arguments object. He refers to it as the arguments array. :)

This was a great video.

I thought to be quite good with RegExp but I didn't know about the lil secret of capturing group with split...

how would you do replace anything after "..."

DUDE,YOU ARE A LIFE SAVER

I love your energy!

REGEX! Baaaaybeeeeeeee yayaaah! :-)

I wonder why are you so happy and super excited!!!!

How would you change the regex without just redefining it?

any advice how to split this string "n1->n2;n1->n3;goal<->n4;n4<-n1" to n1,n2,n3,n4,goal?

can you plz explain it?Please

can substitution construct replace existing pattern to required pattern?

Hello, why does this work in splitting out numbers and text words per every capital letter?
userNameStructure: any;
const userName = '91MickeyMouse';
this.userNameStructure = userName.replace(/([a-z0-9])([A-Z])/g, '$1 $2');
console.log('words', this.userNameStructure);
RESULT: words 91 Mickey Mouse

My goal is to capture Mickey as first name, Mouse as last name. I was thinking I could call a function in place of '$1 $2', but that seems to fall apart.

nice videos! Here's another example that I just came up with of what you could do with replace. let names = {
Marian: "Superhero",
John: "Rescuer",
};

names = JSON.stringify(names);

names = names.replace(/"(\w+)":/g, `"new$1":`);

console.log(JSON.parse(names)["newJohn"]);

Whut you can do that with javascript? Niceee :)) or this:

let names = {
Marian: 2,
John: 3,
};

names = JSON.stringify(names);

console.log(names);

names = names.replace(/:(\d+)/g, function () {
return `:${arguments[1] * 2}`;
});

What?? Ha ha this is too fun.

The comments were 101 but I'm evil

This is very delicious what we learn here. 👨‍💻😋

Exactly what I have needed.

What's to be excited about? yes regular expressions 😉

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

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 :D

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!!!
