Python is already used in the back-end of most web-based applications. However, it does not work with the front-end of web browsers in those applications. This is where Transcrypt comes in. Transcrypt can help create more coherent web-based projects where Python is used to write the back-end and front-end. This course is primarily about using a transpiler called Transcrypt. It translates our Python code to JavaScript and then executes that JavaScript, letting us enjoy the neatness of Python with the front-end flexibility of JavaScript.

Using the Python Transcrypt Transpiler for Front-end Coding

We reviewed the core architecture of a React application, and we also now know how to work with text input boxes in React, as well as how to handle button clicks. The key takeaway here is that any time we have a value that changes in the UI, we should have a corresponding state variable in our code that stores that value. React uses changes to that state variable in determining when the UI needs to be re-rendered.
