Performance matters. <A HREF="https://wpostats.com/" TARGET="_blank" DATA-MSYS-CLICKTRACK="0" REL="nofollow noopener noreferrer">Research shows performance has a huge impact on conversion and user retention</A>. You as a front-end developer can make a big difference! 
In this master class you will learn what makes websites slow and what you can do to make them fast. Step-by-step we will boost front-end performance for our real world example site. We will start with basic optimisations, learn how to automate them and work towards more advanced performance optimisations. Along the way you will learn all about how browsers render web pages.
At the end of the day you will leave with a lot of hands-on experience, which will empower you in your daily work.
We know a lot about performance. We recently rebuilt our own website and wrote <A HREF="https://www.voorhoede.nl/en/blog/why-our-website-is-faster-than-yours/" TARGET="_blank" DATA-MSYS-CLICKTRACK="0" REL="nofollow noopener noreferrer">this blog post</A> about it, which was received well by the community.
