Picking up a new language or framework is always a fun side project, but bringing these into production software at work is always a challenge. It may not be compatible with other technologies you use. The project will need to be maintained for possibly years to come. You will have to convince the rest of your team it's a good idea and they should invest the time to learn.
At Codat, we have used React for our front ends for years but earlier this year we successfully did a project using Svelte. In this talk I will discuss why we decided to use Svelte, how to convince people to use a new language or framework, and why you maybe shouldn't.
