In React, the most powerful and popular feature is Reusability. In that, we can just write code at once and can use them in different scenarios according to our needs. It’s like just creating a Button component and then using the button in any of your other pages with props you need.
When we compare it with other technologies
There are a number of features we can take into consideration while comparing ReactJS to alternate technologies. Some of them discussed below
React performance make it be chosen more efficiently over other technologies as React follows the Virtual DOM (document object model). Virtual DOM makes the content loading faster as it changes only the updated elements instead of recreating the whole DOM.
Easy and quick to iterate
ReactJS also allows you to iterate on any element quickly. Whether you want to modify the color of all buttons throughout the website or want to stop redirecting from each case study to an outdated landing page, it will get done just in a few seconds. Swapping all the old links with the new ones is an easy task. However, if you wish to only modify one or a few components, you can do it without affecting other elements of your project.
Redux to maintain it better
When the file is too large then managing each component becomes complex. Redux is another useful feature of reacting, it is a single source of data which can be accessed over all the applications. So, instead of passing data to each of the components as props we can make use of Redux here.
Error boundaries make easier to control the errors at run time in react. Any of the view layers are facing the error, this will make it quite easy to handle. ComponentDidCatch is a react life-cycle method using which we can handle and redact the errors occurring at run time.
Plenty of debugging tools
Debugging tools in react are often used to debug the application, there are many tools available which can help in debugging.
Difference between Angular and React
- Angular follows MVC structure, while ReactJs is used for the View layer only.
- Angular follows two-way data binding while react uses the state for the input level data values.
- ReactJs uses the concept of Virtual DOM while angular does perform manipulations in a real DOM object.
- ReactJS is lightweight as compared to Angular.
- React offers better performance and flexibility than Angular.
- React is more suitable for light-weight applications and angular is for large UI applications.
Constructor => getDerivedState => DidMount => getDerivedState => shouldUpdate => getSnapShot => DidUpdate => willUnmount
DomCreated => VirtualDomInitiated => DataUpdation => compare Dom with Virtual Dom => DomMounting
At the end…
ReactJS is an open-source library, designed to create engaging and more dynamic web apps. It’s very simple and easy to use, faster and ideal for single page web app development. Above mentioned are some features like Easy to update components, reusable UI elements and virtual DOM that make it stand out of other alternate technologies.
