If I open two browsers and enter different URLs, how does the system know who gets what message? They both have the same IP and Port useage.

What did i do wrong with this const discord = require('discord. js'); var bot = new discord. client(); const token = 'ntm3mjcxmtu1mjg3ote2ntq2.dyogew. dpfiwfpuifzuzvifop-csuxasnm' const prefix = "! " bot. registry. registergroup('simple', 'simple'); bot. registry. registerdefaults(); bot. registry. + '/commands'); bot. on('message', message => { if(message. content == 'hi! ') { message. channel. send ('@everyone sup, how is @everyone day going'); } if(message. content == 'h3lp') { message. channel. send ('dose not have any commands yet'); } bot. on('ready', function() { console. log("ready") }); bot. login(token);
