I've been having trouble with some comma based RegEx creation. In the following structure the first 19 columns should be split only by commas, the next 3 columns have { } but inside these brackets I can have more brackets (it's a "script block"). So for the last 3 I want to have everything inside ,{}

This is the structure

I get the "?" character error when rendering a view.ejs with ejs template engine. here is the source code in nodejs:

I've recently found AzerothCore and I was wondering if it could be configured or modded so that I could play the entirety of WLK with a friend, from start to finish (raids).

Quite a lot of years ago (more than 8) I used TrinityCore to play some WLK raids with friends, but back then I basically had to manually create a buff that would increase HP and Damage, which while made the raid possible in 4-5 players, was really difficult to balance and either it trivialized the raid or didn't make them beatable anyway.

AzerothCore looks like it's one of the most up-to-date and developped WLK emulator and I saw there's a "mod" called "mod-autobalance" that seems to promise just what I need. Before start looking into fixing my Linux server (which is offline at the moment) I wanted to see if my idea to play the game from level 1 to killing the Lich King with a friend is feasible at all and if so, with what compromises.

Lastly, any kind of tip, guidance or advice is greatly appreciated.

Thanks!

I have an HTML table that is populated with some JSON data via JavaScript.

• My table has both negative and positive values. I am trying to color these cells
• Like: if value is in between -100 to -1000 i want to color them with pink
• Like: if value is above -1000 eg: -1500,-1200 I want to color them with red
• similarly if values are positive, like +20,50,200, I want to color the cells green
• And if value is 0 then any other color

I know i can do it with DOM manipulation in JavaScript but I am not understanding the logic to check the values.
