Modern browsers are equipped with advanced features to support web applications.
Web applications have a lot of different features, and to support those features, we need browsers—not just ordinary but modern browsers. For a modern browser to support the advanced features provided by HTML5, it has to implement the HTML5 standard, because it has the latest features and functionalities. There are some versions of browsers that do not support HTML5 majorly because they have not implemented the HTML5 standards, either because they were developed earlier or they choose not to.
Some of the advantages of modern browsers are as follows:
Good performance
Good security
Lesser issues
Faster page loading
Experimental Application Programming Interface or API
Support for latest features
Access to native resources
