Given the situation that you might have decided to move on from your existing tech to React, you might be in a crossroads when it comes to understanding how easy or difficult it may be to accomplish the given migration task. Enriching yourself about the challenges of React migration and its appropriate solution fixes will help you in migrating your web application entirely for continuous improvements in the best way possible. 

#1) Usage of JSX to display data 

In general, JSX provides you with a feasible capability to write simple markups in HTML. But, often with JSX, developers and project managers tend to make mistakes in binding data between the old and new web app, creating new links to necessary old URLs and so on that could have been easily avoided. 

The above obstacle can be resolved by writing components of React using HTML syntax. With the help of using simple curly *{}* brackets to pass data into the elements of JSX, you can easily make the necessary variables of JSX be evaluated as a JS component. This will allow you to pass functions and evaluate React expressions and display data appropriately within any given component during the migration process.

#2) Updating DOM with Form input 

When attempting to shift your existing web app to React, it is common to realize that with React as your frontend you should also manage the data within your old application. Using *React state* to update the UI of your application automatically and updating the existing data using form elements to fork the existing code might not be harder than it seems. 

Leverage the concept of *state* provided by React via *Hooks* to maintain and update the UI of your web app without affecting the existing data. In other words, React state provides you with the power to create dynamic data for your web application. This will enhance the performance of your application since you will be using Hooks to update the state which in turn automatically will update the DOM. 

#3) Recreating layout with React components 

The transition between different tech stacks, libraries, and frameworks is never easy. This is because, when you are migrating your existing web app, you are not only attempting to migrate data, links, images, content, etc but rather you are also required to migrate the entire layout of your existing web app or completely revamp it. This means you have to recreate all Parent and child components as well. 

Use *React props* as parameters to define the child component within every appropriate and necessary parent component. Later, provide input data through necessary React props. Along with the props, use the *StatCard* component in order to create multiple child components. This will support all your dependencies in order to recreate the layout of your new web application. 

The above-mentioned walkthrough is just the tip of the iceberg.
