 const Discord = require("discord.js"),
 bot = new Discord.Client();
 let pre = "?"
 bot.on("message", async msg => 
 var msgArray = msg.content.split(" ");
 var args = msgArray.slice(1);
 var prisonerRole = msg.guild.roles.find("name", "Prisoner");
 let command = msgArray[0];
 if (command == `$preroll`) 
 if (!msg.member.roles.has(prisonerRole.id)) 
 roll = Math.floor(Math.random()*6)+1;
 msg.reply(`You rolled a $roll`)
 else 
 msg.reply(`HaHa NOOB, you're in prison you don't get priveleges!`)
 
 
 if (command == `$prekick`) 
)
bot.login("token").then(function() 
 console.log('Good!')
 , function(err) 
 console.log('Still good, as long as the process now exits.')
 bot.destroy()
 )

Everything works except actually kicking the person. The message sends nut it doesn't kick people. For example, when I type in ?kick @BobNuggets#4576 inactive, it says
@rishabhase has kicked @BobNuggets
Reason: inactive

But it doesn't actually kick the user, which is weird, can you help me?

Change

msg.guild.member(kickUser).kick();

to

kickUser.kick();

also, make sure the bot is elevated in hierarchy

Use kickUser.kick();

I recommend using a command handler to neaten up your code. You don't want all your commands in one .js file.
