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’m trying to check names through an array and I don’t want to have to use
if (<array name>[0,1,2,3,4,5,6,7])
{ code in here }

depend on what you are trying to do u can use forEach or map
let arr = [1,2,3,4,5,6,7,8,9,10];
arr.forEach((item)=>{
console.log(`${item} is greater than 5 : ${item>5}`)
})

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.

Can you help me please to get some param from an URL.
Url should be the form : http.www.lolilol.com/gallery/Param1/Param2/Param3/
I need to get Param1, Param2 and Param3.

A simple solution :
var params = document.location.pathname.split('/').slice(2);
This gives you the array ["Param1", "Param2", "Param3"]

The regex would be http://www\.lolilol\.com/gallery/(.*)/(.*)/(.*)/ assuming you meant http://www.lolilol.com/gallery/Param1/Param2/Param3/
