What is cross-platform development?

Cross-platform development is the process of creating software that can be used on multiple platforms, such as Windows, Mac, Linux, iOS, and Android. There are two main approaches to cross-platform development: native and cross-platform framework. Native development involves writing separate codebases for each platform, while cross-platform framework development allows developers to create one codebase that can be compiled for multiple platforms. While cross-platform development brings many benefits, such as increased reach and decreased development time, it also has some challenges, such as the need to design for varying screen sizes and operating system versions. Despite these challenges, cross-platform development is a popular choice for many developers due to its numerous advantages.
