Working on applications with an old code base that require new functionalities and improvements
along the years can be hard and frustrating for all - developers, product owners and other
stakeholders.

As the application grows, with new modules which are being built on top of old modules that have
also been built on top of other modules by different teams, developers using different technologies,
so does its complexity and maintenance costs. This seriously affects developer’s motivation,
productivity and confidence in fixing bugs or even refactoring old modules.

In this talk I’ll be showing some examples, and hopefully give you some ideas, on how we have been
evolving our application and renewing old modules, how to build some “failsafe” mechanisms so that
you can detect when you accidently broke something that you weren’t expecting.

A cada dia que passa surge uma nova framework no mundo Javascript e, assim sendo, há cada vez mais formas de obter o mesmo resultado com código escrito de maneira diferente.

Nesta sessão vamos explorar os encantos do Javascript na sua forma mais pura, bem como ver as novidades que a linguagem tem oferecido ao longo dos últimos tempos.
