Course Review and Final Comments
Explore a comprehensive review of how to create and apply TypeScript generics in React components for searching, sorting, and filtering data. Understand the practical considerations for using generics effectively and when to use explicit functions instead. This final lesson consolidates your advanced TypeScript skills and prepares you for applying reusable solutions in real projects.
We'll cover the following...
In this course, we have built generic searching, sorting, and filtering functions while also using generics in React components to generate UIs from data types alone.
Generics are a solution, but not the only one
It’s important to remember that while generics are extremely powerful, they are not the automatic, go-to solution for every task. As we saw in this course, searching, sorting, and filtering are indeed possible candidates for a generic solution. However, as we saw with filtering, there can be additional challenges to what it means to filter or when we need to filter out values of a data type.
Generics are most applicable for functionalities that will be used at least twice in an application and are even more useful when the function is used more than that. If the function will only apply to one type and one specific task, then it’s best to build an explicit function for that task.
Congratulations!
Congratulations, you’ve finished an advanced course in TypeScript! Thank you for your time and effort along the way. Please explore the appendix for additional bonus content and other goodies.
Generics as part of your toolbelt
When is it a good idea to use generics in your applications?
For a specific functionality relating to a single data type.
For objects that are complex with many different types and nested objects.
When a functionality or component is expected to be reused at least two or more times in an application with different data types.
