I have a regex which works with DOB: 10-12-1987
I want to refactor is so it accepts a DOB formatted like this: 10/12/1986
export const dateOfBirthValidator: FieldValidator = (dateOfBirth: string) => {
const regex = /^\d{2}-\d{2}-\d{4}$/;
return !regex.test(dateOfBirth);
};

I am trying to write a regex to extract the items in the text below that start with the # and ends with )
const bodyOfText = "#[DataStructures](topic_DataStructures) is one #[Algorithms](topic_Algorithms) branch that could #[Make or Mar](topic_Make or Mar)";
So basically, will want an array that looks like:
["#[DataStructures](topic_DataStructures)", "#[Algorithms](topic_Algorithms)", "#[Make or Mar](topic_Make or Mar)"]
Using string match() we can try:
var bodyOfText = "#[DataStructures](topic_DataStructures) is one #[Algorithms](topic_Algorithms) branch that could #[Make or Mar](topic_Make or Mar)";
var matches = bodyOfText.match(/#\[.*?\]\(.*?\)/g);
console.log(matches);

let valor = value.replace("'","")
valor=valor.replace('"',"")
//or
name=value.replace("'","").replace('"',"")
A better option might be to use a single .replace instead, and use a regular expression to match either ' or ":
const valor = value.replace(/['"]/g, '');

I have a string
var str="[a54hy 8:45pm],[f57gh 9:20]"
i need to get
[f57gh 9:20pm]
I don't want to use split since the string length can be anything
This worked for me. where id is f57gh
var re='\\['+id + '([a-z0-9: ]+)\\]';
var rematch=RegExp(re,'g');
var mydata=str.match(rematch);
alert(mydata); //[f57gh 9:11am]

so i have this array:["bilder/test/_PRF6367.JPG.jpg", "bilder/test/_PRF6372.JPG.jpg", "bilder/test/_PRF6374.JPG.jpg"]
how do i split the individial strings JUST into _PRF6367.JPG.jpg etc.
Use Array.prototype.map to create new array of modified strings:
["bilder/test/_PRF6367.JPG.jpg", "bilder/test/_PRF6372.JPG.jpg", "bilder/test/_PRF6374.JPG.jpg"].map(function(str) {
return str.split('/').pop();
});
Result:
["_PRF6367.JPG.jpg", "_PRF6372.JPG.jpg", "_PRF6374.JPG.jpg"]

how would I check for string
<something> in var string = "some chars <something> somechars"
You can use String.match():
var res = string.match(/<something>/g); // ["<something>"]
If there is no match, the value of res will be null. See example on JSFiddle.
