Difference between Svelte and React
Trend-setter of the JS world
Frontend frameworks: Angular, React, Svelte and Vue
Angular is the second most used framework. At 56 percent, however, it is well behind the front runner React, which is or has already been used by 80 percent of those surveyed. An even greater difference between the two frameworks, however, shows the expressed interest of the respondents: Only 21 percent of the respondents indicated that they would like to learn Angular, while it was 56 percent for React. Part of this result can of course be explained by the fact that Angular is already very well known. However, if one also looks at the development of opinion since 2016, one suspects that the interest in Angular is actually no longer that great. In 2016, when Angular 2 was released, the ratio of positive to negative expressions of interest was still such that Angular was more on the side of the more popular technologies. Around 40 percent of those surveyed stated that they wanted to learn Angular; 13.6 percent already knew Angular and wanted to use it again. Also around 40 percent were not interested in Angular back then, but only 6.4 percent explicitly did not want to use it anymore. In 2020 the picture changed. 67.4 percent of the State of JS 2020 participants said they were not interested in Angular or did not want to use it again. Although this has given rise to a solid user base, Angular is clearly not a trending topic for the majority of the survey participants.

It is also exciting to look at the relationship between frequency of use and user satisfaction. Among the mobile and desktop frameworks, satisfaction is particularly high at Electron, for example, but it is only used by a third of the respondents. This gap between the two evaluation categories was worth a separate visualization for the makers of the report this year:

It shows that only a few technologies can have a high number of users and a high level of satisfaction (in the picture in the upper right corner). This category of technologies includes, for example, React, as well as webpack, TypeScript and Jest. Angular, on the other hand, does not enjoy such high levels of satisfaction, but it is widely used. Most of the tools and frameworks whose users are really enthusiastic can be found on the upper left-hand side of the diagram, which expresses a lower number of users: Svelte is shown there, just like Snowpack and Playwright, but some of the previously mentioned newcomers have also been sorted there . So far, Strapi has only rarely been used, but around 78 percent of users are satisfied with it.
As every year, the creators of the report also presented awards: Testing Library achieved the highest level of satisfaction with 96.59 percent, and TypeScript recorded the greatest increase in users who want to use the technology mentioned again. If you look at which technologies the respondents still want to learn, GraphQL wins the race. IntelliJ IDEA was mentioned most frequently in free input fields.
