Vue.js is an open-source JavaScript framework, similar to React and Angular. It was originally released by ex-Googler Evan You in 2014 who wanted to take what he liked about AngularJS to build a newer and more lightweight framework. Today, Vue.js is a fairly popular and mature framework with an ever-increasing market share behind React and Angular. Here are some of the reasons why Vue.js is great:

Easy to learn
Compared to Angular and even React, Vue.js has a very short learning curve and makes it every easy to pick up regardless of skill level. Someone with fairly basic knowledge of JavaScript, HTML and CSS should be able to start up a Vue.js project with relative ease, making this a great framework for beginners or as an alternative for someone coming across from another framework. The official Vue.js website also provides thorough and easy-to-follow documentation, and a thriving online community of Vue.js developers can help one get a Vue.js web application off the ground in no time.
Lightweight
Vue.js is remarkably lightweight. A minimal "Hello World" application in Vue would be only around 16KB in size, whereas a similar Vue project with every optional feature enabled would sit at around just 27KB. This is much smaller in size compared to similar frameworks such as Angular and React.
High Performance
While good performance can be expected from a well-coded app using any of the major web frameworks, benchmarks have shown Vue.js edges out ahead of Angular and React in many metrics, such as memory usage, startup time, and general DOM manipulation. A developer should expect good performance from a Vue.js app out of the box.
Great Tooling
To set up a Vue.js project, it's as easy as using "create-tool" with Vite and following a few prompts to scaffold an application with all the features you need out of the box. Once set up, the official Vue Devtools extension for Chrome and Firefox allows for easy debugging and inspecting your Vue.js app.
