Hey guys, welcome back to my blog I hope you are doing well.

Today I will help you to know how much javascript you should know in order for you to be prepared to start learning react.

I know for a fact that a lot of people try to search for this because I remember me myself when I started learning react searching for the same thing and never getting a concrete answer.

And the reason for that is because a lot of people who want to learn react are either people who have zero to no experience in programming or programmers who don’t have a lot of experience in web development and they know that react is a very requested, a very in-demand technology and they want to get there as fast as possible.

First of all, is JavaScript even required to start learning React?

Yes, JavaScript is required to start learning React. React is a JavaScript library, so it relies heavily on JavaScript to function. Without a solid understanding of JavaScript, it will be difficult for you to use React effectively.

React uses JavaScript to manipulate the DOM (Document Object Model) and create dynamic user interfaces. It also uses JavaScript to manage state, handle events, and communicate with APIs. In fact, many of the features that make React such a powerful library, such as its virtual DOM and component-based architecture, are made possible by JavaScript.

While it is possible to use React without knowing JavaScript, you will be severely limited in what you can do. You may be able to copy and paste code snippets and modify them to fit to your needs, but you won’t truly understand what you’re doing or why it works behind the scenes which can make it difficult to debug the program. This can lead to frustration and mistakes, and it will hinder your ability to grow as a developer.

How much Javascript do I need to learn?

There are many intermediate JavaScript concepts that can be helpful to understand when working with React. Some of the concepts that are particularly relevant to React development include:

Understanding how to use ES6 features such as arrow functions, classes, and modules.
Familiarity with JavaScript closures and how they work in the context of React components.
Understanding how to use destructuring syntax to extract values from objects and arrays.
Knowledge of asynchronous programming concepts such as Promises and async/await.
Understanding the basics of the JavaScript event loop and how it affects the performance of React applications.
Familiarity with the React component lifecycle and how to use it to manage state and props.
Knowledge of how to use React hooks to manage state and other side effects in functional components.
Understanding how to use Redux or other state management libraries with React to manage global application state.

These are just a few examples of intermediate JavaScript concepts that are helpful to understand when working with React. By mastering these and other intermediate concepts, developers can create more efficient, effective, and maintainable React applications.

How much time to learn React if you know JavaScript?

If you already have experience with JavaScript, you can expect to learn the basics of React within a few days or weeks. However, becoming proficient in React and mastering its more advanced features may take several months of consistent practice.

To become proficient in React, you will need to spend some time practicing and building applications. React is a powerful library with many advanced features, so it will take some time to become familiar with all of its capabilities. Some of the more advanced features of React that you might want to learn include custom hooks, redux (not specific to react though), managing stale states etc.

Ultimately, the amount of time it takes to learn React will depend on your prior experience with JavaScript and your dedication to learning and practicing. With consistent effort and focus, you should be able to become proficient in React within a few months.

Is React harder than JavaScript?

React is a JavaScript library, which means that it is built on top of JavaScript and requires a solid understanding of the language to use effectively. React itself does have its own syntax and features that may take some time to learn and understand, but it is not necessarily harder than JavaScript.

JavaScript is a versatile programming language that can be used for a wide range of applications, from simple scripts to complex web applications. As such, it has a steep learning curve, and mastering JavaScript can take a significant amount of time and effort.

React, on the other hand, is designed to make it easier to build complex user interfaces by providing a declarative syntax and a component-based architecture. While there is still a learning curve involved in understanding React’s core concepts, it can be easier to work with than raw JavaScript when building complex UIs as everything is organised in a much better way.
