Yes, I found learning React JS very easy as it required less initial knowledge to get started. In fact, from my experience React JS is the most beginner-friendly JavaScript library compared to its alternatives Angular JS and Vue JS.

However, React JS had a linear learning curve, hence it becomes more challenging while developing larger projects with complex problems.

Yes, I was able to find a job as a frontend developer after learning React. The frontend developer jobs that I applied required knowledge in one or more latest JavaScript frameworks such as React JS, Angular JS, Vue JS, etc.

In addition, I could also get into mobile development through React Native developer jobs which is the mobile adaption of React JS. Read more about React JS vs React Native from javatpoint.com/reactjs-vs-reactnative.

What do I need to know before learning React JS?

Based on my experience, I would recommend the following prerequisites to learn React JS effectively:

  1. HTML
  2. CSS3
  3. JavaScript
  4. Browser Storage

Similar to simple webpages, React pages are also designed using CSS stylesheets. However, React code is written in JSX which combination of HTML and JavaScript in a single .js file. Further, I needed the knowledge of local and session storage for building some of the applications.

How many days it will take to learn React JS?

In 30 days I was able to learn React JS and develop applications using it. However, it took me almost 3 months to master all concepts of React JS and become prepared for all the interviews.

It is important to note that the time frame is directly dependent on the number of hours spent every day learning React JS. In my case, I consistently invested 2-3 hours every day for the next 3 months to gain significant knowledge in React JS.

Yes, for me learning React JS was worth it both in terms of the number of job opportunities I was eligible for and also the front-end applications I could build.

Learning React JS allowed me to develop web apps a lot faster when compared to using plain JavaScript. Knowledge of the latest frontend library like React JS is very valuable for any employer thus there are ample React JS jobs on the job market.

I learned React JS for the following reasons:

  1. Build large web applications faster with fewer lines of code.
  2. Access external plugins through the npm package manager.
  3. Apps built from React JS have better performance due to the use of Virtual DOM.

I started learning React JS with a crash course video tutorial. The crash course allowed me to get started with a lot of concepts in a short period. Most beginners don’t know where to start with React JS from, a video course is very helpful for them to set up and build their first React JS project.
