Por eso os pedimos que si os apuntáis al meetup sea con la seguridad de asistir al evento para garantizar la charla.

[EN] We know it's summer and maybe many of you are on holidays but Wolfram Kriesing is visiting Valencia and we can't give away this opportunity with an interesting talk about Flow!! That is why we request you if you join the meetup do it with the security to attend the event to guarantee the talk.

Abstract:

Ever wondered how to add types or even strict typing to your JavaScript code? I will try to explain typing and also how it works using Flowtype, which is a static type checker for JavaScript. Not only will we see how it works, but also how your code and your programming can benefit from it. Benefit from types? Oh yes! Remember the last time when a variable that (actually) must be true or false became 1 and all the code broke? What if we could make this something of the past? And you bet we can. But that is just one benefit, get ready for more! We will use Flowtype which has type inference, so not every variable needs to get a type, just some. And the best we will get exhaustiveness checks. What? Let’s explore it together. And let’s also explore what might come after you mastered types with JavaScript.

About Wolfram Kriesing:

From Munich with strong bonds to Valencia, actually German but feeling some Spanish blood in my venes. The sun just shines for me when I can TDD some JavaScript, those are the two things I do best. That’s why I came up with things like es6katas.org and I started the JSCodeRetreat and still run it… I just care about the JS community to care about their skills. And I love to spread the word about it and pair program with anyone who also cares. So let’s pair or mob-program together.
