CSS Is more powerful than we usually give it credit for. Let's see together how we can make use of CSS to build together fully functioning filtering capabilities into an emoji-picker component, improving performance while at it.
We will use some old and new techniques, and combine them in creative ways to turn a slow, laggy experience into a responsive and modern searching capability.
We'll learn about the advancements in CSS, and discover the untapped potential of CSS for building dynamic UIs.

In the talk I will explain the pains and problems of form validation Then I will explain the mental model of unit tests, and compare it to how we think about form validations.I will introduce vest with a bit of live coding showing its unit testing syntax.

Forms on the web have always been with us, yet it still feels like you always have to fight them to make validation work as you planned - and even with the significant improvements modern day libraries and frameworks give us, maintenance is mostly a hassle.Vest is a new breed of form validations framework. It draws its syntax and style from Unit Testing frameworks like mocha or Jest (hence the name), which brings the elegance and declarative nature of these frameworks to the world of form validation, greatly reducing the overhead it takes to write, maintain and reuse validations in your JS apps.
