Which JavaScript framework should I learn 2022?

Conclusion. React remains the most popular JavaScript framework, especially when looking at NPM downloads. Its ability to be used for larger and smaller projects helps keep it popular. Svelte and Vue may be the newcomers, but they've seen big numbers in terms of popularity growth.

Do classes exist in JavaScript?

In JavaScript, there are no classes in the class-based OOP sense of the word. JavaScript works with objects. If you want to encapsulate a few functions and properties together, you would create an object containing functions and properties, and not a class.

Do I need classes in JavaScript?

In JavaScript, you don't! You can write any program you want without utilizing classes or the this keyword ever! Indeed, the class syntax is somewhat new to JavaScript, and object oriented code was written with functions beforehand. The class syntax is just syntactic sugar over that function-based approach to OOP.

Will JavaScript be the future?

JavaScript is likely to still exist in 10 or even 20 years. However, just like the hammer that has been in the family for 60 years but got 3 new handles and 2 new heads; it may well evolve massively from the language we know and love today.

Is It worth learning JavaScript in 2022?
