A minimalist (amateur) implementation of 'Vector', along with cosineSimilarity

//TODO: Check things?
this._values = VectorArray;

toArray() {

get length() {

Things to remember if you're writing an extension and trying to get Google Analytics working.
  • When setting up your Analytics property, you can pick any domain. You could go with example.org, if you don't have one.
  • There are multiple variants of Google Analytics scripts. You want to pick analytics.js: https://www.google-analytics.com/analytics.js
    Pick analytics.js
  • Add the domain to your content security policy in the manifest { "content_security_policy": "script-src 'self' https://www.google-analytics.com; object-src 'self'" }
  • This code works. It's intended for a background/event page: 
    window.onload = ()=>{  
    window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date;

ga('create', 'UA--', 'auto');
