title: Variables in SPFx projects?
body: <p>I'm working on a web part using SPFx with React framework, the presentation layer in on a file called Refiner.tsx, while on the other hand I have my logic on a another file called RefinerWebPart.ts.</p>
  
  <p>How do I get a "global" (for the lack of better term) to be accessible on both modules?</p>
