Reason to write this

When I look up jobs in "LinkedIn Jobs", I found that there are so much ads posted by job agent. I used so much time every day to filter out these ads. Therefore I wrote this code.
This code is written by pure JavaScript and no 3rd library is used. I tried it on Google Chrome only and it seens that can work on other browser.

How to use the code

1. fill your agent list into variable "agentList"

let agentList = [
  "ADD YOUR LIST INTO HERE"
];

function highlightAgent() {
  document.querySelectorAll("a[data-control-name='job_card_company_link']").forEach(function(currentValue) {
    let name = currentValue.text.trim();
    let agentName = agentList.find(function(input) {return input === name});
    if (agentName !== undefined) {
      currentValue.style.backgroundColor = "#FF0000";
    }
  });
}

window.setInterval(highlightAgent, 5000);

1. paste the code into "Console" of "DevTools" (assume that you are using Google Chrome). The highlight function will be run in every 5 seconds, so you can see result at most 5 seconds after you press next page.

It is in active when you press next page, unless you press "reload" of browser.
