8 Performance Analysis Tools for Front-End Development. Recommended tools to test and analyze your frontend code performance.

You can have the most beautiful and engaging website in the world, if it does not load quickly on the browser, people would tend to skip it. Although there are many performance rules out there, at the end of the day, it all comes down to load time.

According to Jakob Nielson, here are things you should remember when building your website.

In today's front end web development project tutorial we will talk about rotating shapes, images and particles with plain vanilla JavaScript on HTML canvas. Today we will build a beginner friendly particle system project together from scratch and in the process we will learn how to replace particles with images using draw image canvas 2d api method and how to make these images rotate around using 4 built in canvas methods - save, translate, rotate and restore. Let's bring our HTML canvas projects to the next level by mastering these techniques, welcome to another episode of my vanilla JavaScript creative coding series.
