i want remove all ',' from my string with regex in javascript.
this is an example from my string:
45,454,545
and i want my string convert to this:
45454545

Comma isn't a special character in regex, so you can just use /,/. Add the global flag and you're done.
console.log('45,454,545'.replace(/,/g, ''))

Try this,
var str = "45,454,545";
var res = str.replace(/,/g, "");
console.log(res);

I'm wondering how to show the first two characters and replace all last character of a string by symbol *.
Ex: 121,121,121 -> 12x,xxx,xxx .
Thanks

I love using regex when it comes to replace string according to some pattern.
var p = '121,121,121';
var regex = /(?<=.{2})([0-9])/gm;
console.log(p.replace(regex, 'x'));

You can use substring and regular expression. See the sample below.
var str = "121,121,121";
var res = str.substring(0, 2) + '' + str.substring(2, str.length).replace(/[0-9]/g,"x");
alert(res);

Just use substring and replace with a simple regex (to single out digits and keep commas and other punctuation):
const str = "121,121,121";
const obfuscated = `${str.substring(0, 2)}${str.substring(2).replace(/\d/g, "*")}`;
console.log(obfuscated);

I have a string like that header#top.header.header--show-offset and I'm struggling to know how could I split it into something like [ 'header', '#top', '.header', '.header--show-offset' ]
Thank you!

You can use regex:
let str ="header#top.header.header--show-offset";
// Keep the delimiter
let res = str.split(/(?=[#.])/gi);
console.log(res);

I would do this in two steps:
Replace id and class symbols with a comma and then the symbol
Split the resulting string by comma
var selectorString = "header#top.header.header--show-offset";
selectorString = selectorString.replace(/#/g, ",#")
selectorString = selectorString.replace(/\./g, ",.");
var selectorList = selectorString.split(",");
console.log(selectorList);

I have the String:
Name01: Name02 - Project Name (Client) - Infos
Using JavaScript, what is the fastest way to parse this into:
Name01
Name02
Project Name
Client
Infos

You can replace your string with a common character where ever you need. So that you can split on them. Try the following way:
var str = "Name01: Name02 - Project Name (Client) - Infos"
str = str.replace(/[-()]/g,':').split(':');
str = str.filter(i => i.trim()).map(j => j.trim());
console.log(str);

This isn't perfect but its simple:
const str = 'Name01: Name02 - Project Name (Client) - Infos';
const matches = str
.replace(/[^\w\s+]/gi, '')
.replace(/\s\s+/gi, ' ')
.split(' ');
console.log(matches);
The issue here is keeping the space between Project Name.

I need to split${SOMENAME} (${THISNAME}) ${THESENAME}
I just need to extract the words SOMENAME THISNAME and THESENAME from the above string. Is it possible?

You can pass in a regular expression separator as part of the .split() function.
var string = "${SOMENAME} (${THISNAME}) ${THESENAME}";
var re = /\W+/;
var arr = string.split(re);
document.write(arr);
Take a look at String.prototype.split for more information.

If you only need extract the words, this could be a simple solution:
var s = "${SOMENAME} (${THISNAME}) ${THESENAME}";
var words = s.match(/([A-Z])\w+/g);
