Keeping up with the Web
Keeping up with changes in web technology and the web as a platform is one of the toughest challenges you will face as a web developer or designer.
Design trends change and technologies evolve all the time. All of the browser vendors are continuously improving their browsers on desktop and mobile, bringing out new features and improving user and developer experience with new tools and capabilities.
Several browsers are made available to developers during their development cycles, and these can be useful to a developer as they let us use experimental features and see what is changing in the next release. We can keep an eye on upcoming changes and see what effect they may have on our websites, and we can act accordingly rather than having to react in an unplanned manner when the browser updates.
