JavaScript is one of the most popular programming languages in the world.Along with HTML and CSS, JavaScript forms the basis of front-end web development, allowing the creation of interactive elements.JavaScript brings the familiarity and comfort of Object Oriented Programming concepts into web development. It brings a lot of dynamic functionality to web pages and makes a website much more intuitive and interactive.JavaScript is used as much as it is talked about. A lot of data interpretation platforms verify that it is the most successful technology in the engineering world․ JavaScript is the most popular programming language with the number of opened pull requests. Pull requests are an indicator of the quantity of code being written. It’s entirely different than any other programming language because it’s designed adequately with model/view isolation. So, the reason I love JavaScript so much is that you wouldn’t use it for the wrong task, because you also have HTML and CSS on your side.

Most of the websites on the web are powered by AngularJS or Angular 2 versions. Above 25% of javascript developers are currently using Angular. And it was also Ranked 3rd most popular front-end javascript framework in the JS survey. Angular is one of the most powerful, efficient, and open-source JavaScript frameworks. It is a TypeScript-based open-source web application framework which is led by the Angular Team at Google and by a community of individuals and corporations and is a complete rewrite from the same team that built AngularJS

To build successful JavaScript applications, you need to keep these points in mind:

• Try Learning everything you can about the JavaScript language itself. Its bad parts and right parts and all the modern features it recently gained.
• Learn JavaScript runtimes like Node and Browsers and learn how they are single-threaded. Learn their APIs. And also how to share code between clients and servers. Learn about the event loop. Understand VMs call stacks.
• Master the merits of functional programming and use its concepts where you can. Discover how to be declarative instead of imperative when you can.
• Learn small libraries like React and Redux, which do one thing and do it well. Pick libraries with the minor API.
• Learn how to build scalable data APIs 
• one should learn the power of CSS, how to use it to minimize your applications JavaScript code.
• Learn how to add types to JavaScript with TypeScript (or Flow) and learn where you should focus on types vs testing

Becoming better at JavaScript is a great goal, and that's the one thing all web developers always strive to accomplish. In order to meet this goal, it can be helpful to be strategic about what you wish to accomplish and learn. I have found that it's important to remember your reason for wanting to become better at JavaScript. This allows you to re-visit your why if you get stuck, and it can be a powerful way to stay motivated. With that in mind, I will offer a process you can use. It is a very general framework, which I hope will allow you to plug in your own goals and keep moving forward

Let's look at some points which will help us to be better at JavaScript:

1. Evaluate Local Variables
2. Create shortcut codes to speed up coding
3. Manipulate element fragments before adding them to DOM
4. Save bytes by using Minification
5. Don't use nested loops if not required
6. Cache objects to increase performance
7. Use a .js file to cache scripts
8. Place JavaScript at the bottom of the page
9. Use jQuery as a framework
10. Compress your files with GZip
11. Don't use "With" keyword
12. Minimize requests for HTTP

ReactJS is an open-source JavaScript library used for building user interfaces specifically for single-page applications. It is always used for handling the view layer for mobile apps and web. React allows you to create reusable UI components. Beginners can also learn reactJS.There is no way to learn something the easy way, and that's why it takes time to learn React as well. However, to make it simple, learn React only step by step and don't get yourself distracted by any other tech in this learning process.

The following things should be considered to learn reactJs:

1. It would be best if you had a good understanding of HTML/CSS.
2. You will need a quite good knowledge of JavaScript first in order, to begin with, React.
3. Basic understanding of JS frameworks is also necessary.
4. Always use books, tutorials, video lessons, webinars, etc. for learning React and related technologies.
5. Go for online React tutorials.
6. Practice regularly.
7. Reading best React books helps us understand the underlying concepts.
8. You can watch online video lessons and attending web seminars

And we highly recommend you just to start coding and even if you make mistakes google it and learn. This always makes you improve your knowledge of coding. You can also seek help from other people who know how to code.

We all know that JavaScript is one of the most common programming languages in the world, which is used historically for front-end web development. But because of various other introductions of different frameworks, its use cases started to expand dramatically. Eventually, this led to a massive demand for high-quality JavaScript developers, by which a large number of people began searching for the best way to learn JavaScript.

It is essential to realize that the learning methods will be different for each and every person. Everyone is different, and everyone learns differently. So by all means, the best place to learn JavaScript online is an online course. These online courses are generally designed with versatility and self-paced learning in mind. Instead of following a stringently structured course and acquiring things when and how you’re told, you will have a lot more freedom to find the most proper way to learn JavaScript for yourself and to do things the way you want. Still, usually courses like this tend to be too broad and might also teach you details that are not very needed when you start coding. And instead of learning at your own pace, you’re required to follow a strict curriculum. It is therefore essential for you to understand the different ways to learn JavaScript online, and you can mix up them to create the best place to learn JavaScript online for you.
