如何获取特定 Discord 角色的名称？

Question

I am trying to make a bot for my server with many international users. One issue we always run into is coordinating times because were all around the world. I wanted to make this bot be able to tell you what time it is for a specific user. I already have all of my users have a role with the format "UTC[-10 through +14]" that says what time zone they are in. I already have the function that when you give it a UTC offset, it will give you the time there. My question is, how can I get the UTC offset of someone given their name. For example, I have a user @User1#0000 with the role UTC-05 . They also might have other roles (not timezone roles). How can I get that -05 out of someones roles just given their name?

Firstly, to get a member's roles, you just need to use the roles property member , now to get just the timezone role, you can use the .find function that collection has and look for "UTC" at the start of the role name,

let utcRole = member.roles.find(role => role.name.startsWith('UTC'))

Now, the harder part is parsing the role name to get just the offset from it, we can do that using a regular expression and the match function, we want to isolate the +14, the regex for isolating it would be [\+\-][0-9]*[^\[\]] , so adding that to our sudo code,

let utcRole = member.roles.find(role => role.name.startsWith('UTC'))

let offset = utcRole.name.match(/[\+\-][0-9]*[^\[\]]/)[0]

And there we go, you will have the offset that you wanted, now one important thing to remember is that you have the offset as a string, and by what you said you will use it as a number, to convert strings in to numbers in javascript we use parseInt() , so to convert it to a number,

let number = parseInt(offset)
