React Native, a popular framework developed by Facebook, has revolutionised mobile app development by significantly shortening development time, which in turn makes app creation more cost-effective. This framework allows developers to write code once and deploy it across multiple platforms, including iOS and Android. This “write once, run anywhere” approach eliminates the need for maintaining separate codebases for each platform, thereby reducing development efforts and costs.

One of the primary ways React Native shortens development time is through its use of JavaScript, a widely-known programming language. Many developers are already familiar with JavaScript, reducing the learning curve and accelerating the development process. Additionally, React Native boasts a vast library of pre-built components, which developers can leverage to quickly build and implement various functionalities within the app.
