Use of AngularJS Vs React JS
Let’s look at the React JS vs Angular JS comparison in the table underneath.
|Technology||React JS||Angular JS|
|Data Binding||1 way binding||2 way binding|
|Dependencies||Needs additional tools to handle dependencies||Handles dependencies automatedly|
|Last version||React 15||AngularJS 1.6.0 RC2|
Comparison on the basis of Performance Levels
On performance levels, Angular 1.x and higher depends on two-way data binding. This concept is a foundation of “dirty checking,” a method that can turn your AngularJS application laggy. AngularJS builds a watcher for every binding to monitor changes in the DOM.
Once the View updates and turns “dirty,” AngularJS compares the new value with the bound value and executes the $digest loop. The $digest loop checks the values and changes. The loop doesn’t stop working waiting it checks all watchers and applies all needed alterations to both the View and the Model. This is why performance goes down. Unlike React, an AngularJS Development Company applies modifications in the real DOM in the browser.
Now, as a substitute of sending entirely new HTML to the browser, React sends the HTML only for the altered components. This systematic approach is much more proficient than what AngularJS provides.
In relation to one-way data binding, React doesn’t utilize watchers to monitor modifications or changes in the real DOM. So, React makes it easy to control application performance. But this doesn’t mean we cannot generate a quick application in AngularJS.
Both AngularJS and React are useful for writing single-page applications. However, some developers may say that React is superior to AngularJS and vice versa. What’s in fact best for a given project, however, depends on how you use these technologies.
