TypeScript is a superset of JavaScript which primarily provides optional static typing, classes, and interfaces.

Over the past few years, TypeScript has gain immense popularity among frontend developers. Improved maintainability, code consistency, and future browser support are few reasons behind its success. Though many other frameworks and libraries adopt TypeScript by default, React remained neutral, giving the developers the option to choose between TypeScript and JavaScript.

In this article, I will be going through 5 strong reasons for you to consider TypeScript for React applications. Besides, I will also highlight common challenges for you to better prepare for the journey.

1. Easy to read and understand components

With TypeScript, it’s easy to define Prop types, making the code much easier to read and use. And this will accompany by IntelliSense support plus static type checking.

These, in combination, make it a great development experience and reduce the potential for bugs. Besides, adding comments to Prop types also adds more readability when you check a component definition.

import React from 'react';

export interface Props {
    /** name of the super hero */
    name: string;
    /** age of the super hero */
    age: number;
}

export const Avatar: React.FunctionComponent<Props> = ({ name, age }) => {
    return (
        <div>
            <h1> Name : {name} </h1>
            <p> Age : {age} </p>
        </div>
    );
};
