Meet the #ReactDayBerlin MC @robinpokorny:  #ReactJS #Jest

  • There are a few initiatives that come to mind: For one, there’s WebAssembly with which you can have some really low level language in the browser, and that’s great, because we’ll be able to create more powerful stuff compared to nowadays, when we’re mostly dependent on JavaScript.The other improvement could…
  • What’s your most awaited feature in testing tools?Obviously, Jest will never be completely automated, on the other hand, if you look at snapshot testing, that kind of is Jest is doing a major part of the job, generating something that you only manage and approve changes.

  • Now some developers will say that i’m storing too much inside my state object, but personally I like to keep all of the relevant data to my component inside that components state.
  • Lets explore our example of the list of items component and see what it might look like:As you can see, the state is where all of our data is stored inside our component.
  • When addItem is called and it performs the setState function on the component, the components state will change, and thus trigger the component to re-render according to the new state object, thus including the new item in the list.
