Popular frameworks such as React, AngularJS, and Vue.js are gaining and losing a legion of followers but still manage to rank top in best JavaScript frameworks, while few new competitors have been gaining ground recently to challenge the big 3.

ICONS fonts Vs SVG ICONS

Before the discourse of icon fonts vs SVGs, when browsers had non-existent CSS support, images were the only way for developers to showcase icons using the classic tag. Here is an example of an image icon.

<a href="contact-us.html">
       <img loading="lazy" src="mail.jpg" alt="email" />
</a>

Icon fonts are vectors making them scalable to any resolution, still they are not free from snags. Using icon fonts can lead to the generation of multiple server requests and can also lead to invisible text flashing during the period when font libraries are still loading. If the browser for some reason does not comprehend the icon font, a blank space is displayed. This is the reason why a lot of developers prefer the latter in icon fonts vs SVG icons.

Dev tools may launch either docked to a side in your browser or they can be free floating.
