title: What's the difference between tsc (TypeScript compiler) and ts-node?
body: <p>I'm very confused about the difference between <code>tsc</code> and <code>ts-node</code>. I'm learning TypeScript and I usually transpile server <code>.ts</code> files with <code>tsc</code> command.</p>
  
  <p>Now, I'm approaching <a href="https://nestjs.com/" rel="noreferrer">nestjs</a> framework, and I see that it uses <code>ts-node</code>.</p>
  
  <p>So what's the difference between the two? Which one should I use?</p>
