Using TypeScript with React
During my internship we&#x27;ve built a large prototype using React+Typescript, and here are some of my key take aways from it:<p><pre><code>  - Quite often when using unreleased APIs, you turn to using &quot;any&quot; all over the place.
  - Development time is slower than writing in regular JS&#x2F;React. This started to become a major issue due to the nature of our project being a prototype (fast iterations on ideas and features). 
  - Lots of frustration when a package doesn&#x27;t have types (although most major ones do have them).
</code></pre>
Otherwise it has been a joy writing the application, and it does &quot;document&quot; your components significantly better.
