State of JavaScript is an online survey that since 2016 collects and analyzes data from JS developers to detect the current trends of ecosystems and identify the upcoming trends. Quite interesting! A couple of days ago the 2022 version was released and the results are quite interesting.

React continues to be very strong both in number of users and its retention ratio (percentage of users who would use a library again). I have been lucky to work with this library in the last years of my professional life and despite its drawbacks, I can understand why it is still quite appealing.

It is also interesting to see what happens with the other two big ones (Angular and Vue.js):

While Vue.js has similar retention levels to React, its number of users has not yet reached the same levels. Angular.js’s interest and retention levels are really low. This is surprising given that it is still one of the most sought after frameworks in the industry.

Some weeks ago when I finished working, I was about to leave the building and I saw in the wall a sheet of paper with information about a vue.js meetup here in Berlin. I thought I had never heard about this vue.js and the more I read, the more interested I became in this front-end javascript framework.

Google Search trends show vue.js has been the most popular framework in the last 12 months. Vue.js is self-described as "a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable". I gave it a go and it's quite interesting.

I have been using Python for many years and I recognize how powerful it is with libraries like Pandas and Scikit-Learn for Data Science. In a previous role, I had the opportunity to use R, but I haven't touched it in a while. I was curious to see what the interest is in R vs Python in the Google Search Trends. You can see the graph above plotted with this data source.

Last weekend I finished converting the FX calculator I developed during my career break to React.js. I have briefly touched some code at work but I wanted to get my hands dirty and understand better the advantages and the challenges of this library.

I was also checking today some interesting [Google Trends data](https://t.co/aCOxxTOhUo) about the most popular JavaScript frameworks in terms of search interest, and React is definitively winning the interest war.

I was discussing it with a colleague a couple of days ago. The Facebook React is definitely going to stay around. Look at the previous graphs showing the increase in Wikipedia page views during the last year and the trend increase in Stack Overflow.
